On May 10, 2017, NBC canceled Timeless. Three days later, the show was brought back from the grave much to the delight of its devoted fans. Timeless was renewed for a ten-episode second season and then canceled once again after the season finale. The fans, nicknamed "Clockblockers" fought like hell to get the show renewed, but NBC wouldn't budge. However, a wrap-up movie was ordered and it's expected to air in December 2018. Timeless, in case you're not up to speed, is a show about a team of time-travelers attempting to stop a mysterious organization from altering the course of the country's history in order to advance their sinister goals. If time travel is your cup of tea, give this show a chance even if it is canceled, because at least it will get a proper ending. Unfortunately, many great shows in the past weren't as lucky. Networks can be ruthless, which has resulted in a number of awesome shows getting axed way too early without providing any closure.

On the flip side, we're living in the age of reboots, so there's always a chance that the next show to make a surprising comeback will be your favorite. These reboots are happening left and right whether we like it or not. Charmed, Murphy Brown and Queer Eye are just some of the shows that have been rebooted recently. Since this trend shows no signs of stopping, here's a list of sci-fi shows that we'd either love or hate to see rebooted.

20 WANT: BLADE

Blade TV

Before there was MCU, Blade was one of Marvel’s most successful franchises. Starring Wesley Snipes as the titular vampire hunter, the 1998 Blade movie set the stage for future superhero movies. The movie franchise spawned a short-lived TV series starring Kirk Jones, which ran on Spike.

That revival didn’t find success in part because the violence and gore from movies needed to be toned down for TV, however, that shouldn't be a problem on a streaming service. If Marvel were to remake Blade on Netflix or Hulu or whatever, there would be no need to tone anything down. Plus, it would bring Blade into the MCU which would be quite refreshing.

19 DON’T: BIRDS OF PREY

Birds of Prey

Way before the Arrowverse was a thing, the WB network ran a Birds of Prey show. Centered around Helena Kyle/Huntress, Barbara Gordon/Oracle and Dinah Redmond (nee Lance), Birds of Prey was set in New Gotham City several years after it was abandoned by Batman. The pilot had impressive ratings, but they swiftly dropped and the show was canceled after only 13 episodes.

Given the success of The CW’s Arrowverse it may seem that now is the perfect time to bring back Birds of Prey, however, there is such a thing as too many Arrowverse shows. We’re already at six -- counting both Black Lightning and Batwoman -- and seven would be one too many. Plus, Warner Bros. is making a Birds of Prey movie (probably).

18 WANT: DOLLHOUSE

Dollhouse

Joss Whedon has created countless of our favorite shows and movies, and he is considered by many as the “nerd god”. While his record may not be spotless, he’s certainly a writer and director whose name we’re always glad to see attached to a project. His most popular TV show is probably Buffy the Vampire Slayer, but he did create other shows worthy of our attention.

The short-lived sci-fi series starring Eliza Dushku, Dollhouse, ran on Fox between 2009 and 2010 for two thirteen-episode seasons. The show followed Dushku’s character Echo, a Doll with a temporary personality, on her journey toward self-awareness. The show ended prematurely and deserves a second chance.

17  DON’T: THE TOMORROW PEOPLE

The Tomorrow People

If at first you don't succeed, try again. If you fail again just stay down. At least that’s our advice to The Tomorrow People. Originally a '70s British television series, The Tomorrow People was already rebooted twice. First as a kid’s show in the '90s. Then, in 2013, the show got a US reboot on The CW.

The latest reboot lasted only one season due to poor ratings. It would be nonsensical, to say the least, to attempt to bring it back once again. Especially now that there are superpowered individuals left and right on any given network.

16 WANT: TERMINATOR: THE SARAH CONNOR CHRONICLES

Terminator The Sarah Connor Chronicles

Fox’s short-lived series Terminator: The Sarah Connor Chronicles had a rough start but once it found its way it turned into a complex, character-driven and exciting story with a lot potential. Unfortunately, that wasn’t enough for Fox to keep it around, so The Sarah Connor Chronicles got the ax after only two seasons.

Since the Terminator movie is getting a reboot next year, perhaps it’s time to give the show another shot. The original series, short as it was, had a loyal following. If The Sarah Connor Chronicles was to make a comeback we’d gladly add it to our watchlist.

15 DON’T: LIMITLESS

LIMITLESS

The spin-off to the 2011 Bradley Cooper film Limitless, based on the Allan Glynn novel The Dark Fields, premiered on CBS in September 2015. The show starred Jake McDorman and Dexter alumna Jennifer Carpenter as the NZT-infused FBI consultant Brian Finch and his handler FBI Agent Rebecca Harris, respectively.

Relying on a tired concept, Limitless didn’t have much to offer despite having a solid twist. The show looked polished, but the plot-hole-ridden episodes, poorly developed characters, and at times horrible humor rendered Limitless unwatchable. Just, go watch “Stop Me Before I Hug Again” and you’ll see why this show needs to stay gone.

14 WANT: FOREVER

Forever

Four years ago, ABC premiered a show starring former Mr. Fantastic, Ioan Gruffudd, as the immortal Dr. Henry Morgan. Every time Dr. Morgan passes away, he wakes up near a body of water completely naked. It goes without saying his immortality is a tightly kept secret. As New York City’s best medical examiner, Henry teams up with Detective Jo Martinez to solve New York’s most interesting murder cases. As the duo investigates cases, Henry's long life unravels through flashbacks.

Forever was a well-written, well-acted and addictive show that had the potential to become the new Bones or Castle. Sadly, due to lower ratings -- but, mostly network politics -- season two wasn't greenlit. But, it's never too late to bring it back and we're not giving up hope.

13 DON’T: LOST

Lost

Not so long ago there were rumors about a possible Lost reboot. Given the current state of television where almost everything is a reboot, a remake, a revival or a rip-off, it wasn’t hard to imagine Lost coming back. Fortunately, though, the rumors have since been shut down by ABC.

Lost is a classic, there’s no doubt about it. It changed the way we watch television and the way television is made. A number of shows have attempted to emulate Lost. Some found success, some failed miserably. But, a Lost reboot would more likely fall with the latter. Lost is a divisive show -- mostly due to the finale -- however, that finale provided a cathartic conclusion to a story that really requires no further exploration.

12 WANT: FLASHFORWARD

Flashforward image.

In 2009, on the heels of Lost’s success, ABC premiered FlashForward. The character-driven, disaster-style mystery was supposed to be ABC’s next big thing. The show focused on a cataclysmic event during which everyone on the planet lost consciousness for 2 minutes and 17 seconds, while also seeing what their lives will look like six months in the future.

Sounds promising, and it was. Though the show did struggle a bit in the beginning (but, honestly, most do), it still managed to deliver a pretty interesting, bingeable and sequel-worthy first season. Unfortunately, ABC decided to call it quits, leaving us with tons of unanswered questions. If anyone decides to bring this show back, you can be certain we'll be watching.

11 DON’T: HEROES

Heroes

Heroes could have been a classic. Emulating the aesthetic style and storytelling of comic books, the show told the stories of ordinary people from all walks of life who discover that they have superhuman abilities. “Save the cheerleader, save the world,” that was the mission. The line was repeated so frequently that it became a pop culture phenomenon.

Unfortunately, the writers couldn’t keep up the top-notch storytelling and character development for too long and the show started to dwindle pretty fast. Heroes was canceled after four seasons, then brought back as an event mini-series Heroes Reborn in 2015. But, the mini-series was no Heroes season one and it received mixed-to-negative reviews. Another reboot would be superfluous.

10 WANT: SENSE8

Sense8

Written by the Wachowskis and J. Michael Straczynski, Sense8 was a Netflix sci-fi drama that ran for a total of two seasons. The show followed eight strangers from all around the world who suddenly became mentally and emotionally linked. What separated Sense8 from most sci-fi shows is the way the series explored themes like, identity, gender, and religion.

Both seasons received positive reviews and the show developed a loyal following. Still, Netflix decided not to proceed with season three. It would be a shame to let this show end so abruptly and we’re hoping it comes back soon.

9 DON’T: INHUMANS

Inhumans

Marvel’s Inhumans was an ambitious project, but the first live-action television series to be released in IMAX failed to live up to expectations. The eight-episode season was met with unfavorable reviews -- to put it mildly -- and very low ratings, so ABC pulled the plug in May 2018. Yet, despite mostly negative sentiment surrounding the show, there is a petition to save Inhumans.

The petition brings up Agents of S.H.I.E.L.D. as an example of how a show can have a lackluster first season and still become great, which is a fair point. But, it’s not that Inhumans don’t deserve a second chance, however, a reboot can certainly wait a few years. At least til the dust to settles around this failed adaptation.

8 WANT: THE SECRET WORLD OF ALEX MACK

The Secret World of Alex Mack

You know the story: Alex Mack was an average teenager living in Paradise Valley when one day, while she was walking home from school, she nearly got hit by a truck carrying a top-secret chemical that spilled all over Alex giving her powers, such as telekinesis, shooting electricity from her fingers, and the ability to liquefy. Struggling to keep her powers a secret, handling unpredictable side-effects, and navigating the everyday life of a junior high student, all that was the wonderful Secret World of Alex Mack.

If you grew up in the '90s this was probably one of your favorite shows to watch. The series was a success and ran for four seasons. Perhaps a reboot, remake or a revival is in order.

7 DON’T: FRINGE

Fringe

Created by J.J. Abrams, Alex Kurtzman, and Roberto Orci, Fringe premiered on Fox in September 2008. The five-season series stands as one of the best sci-fi shows of all time, despite having been considered an X-Files clone in the beginning. Fringe was, first and foremost, a show about love, connection, and family. The show’s ending, though you may consider it premature, was meticulously crafted in a way that it left us feeling content and fulfilled.

The story of Walter, Peter, and Olivia was exciting, heartfelt, and thoughtful, but it had a fitting end. To retread already studiously explored themes and concepts would be pointless. To disturb characters whose chapters have been closed would be even more pointless. Good things come to an end, and that’s perfectly fine.

6 WANT: BUCK ROGERS IN THE 25TH CENTURY

Buck Rogers in the 25th Century

Inspired by the overwhelming success of George Lucas’ Star Wars, Universal Studios developed a television series starring Gil Gerard as Buck Rogers, the time-displaced space shuttle captain. 500 years in the future, Rogers becomes part of the militaristic Earth Defense Directorate. Gerard’s co-star, Erin Gray portrayed Col. Wilma Deering who is considered one of the first feminist characters on TV.

The show maintained high ratings during the first season, but failed to do so in the second season, so NBC canceled it. Buck Rogers came to an end over three decades ago and perhaps it’s time we revisited it. A modern take on the old space drama with all the technological advantages at our disposal.

5 DON’T: SMALLVILLE

Smallville

Recently, there have been some rumors about The CW possibly developing a Superman series starring Tyler Hoechlin. However, these have been promptly shut down. On the other hand, before Hoechlin even debuted as the Arrowverse Superman, many fans clamored for Tom Welling to reprise the role he played for ten seasons on Smallville.

Even though Smallville was a solid superhero show (one without which the Arrowverse possibly wouldn’t even exist) and Welling was a great Clark Kent, we’d pass on a Smallville reboot. The show, with all its virtues and flaws, came to a natural and rather satisfying conclusion. Besides, we have Supergirl now and she’s just as good as her cousin and it's finally her time to shine.

4 WANT: FIREFLY

Firefly

You all knew this was coming, so let’s just get it done. Firefly is one of the greatest injustices in TV history. Joss Whedon’s space Western developed a cult following, despite its tragically short run. With an engaging cast of characters, an intricately crafted world, and Whedon’s trademark wit, Firefly was unlike anything else on TV at the time.

Much to our dismay and displeasure, the show was criminally mistreated by Fox, which failed to promote it properly, aired the episodes out of order, and then canceled the series due to low ratings. The 2005 film Serenity provided some closure, but we’d still love to see this show rebooted and given a proper chance to thrive.

3 DON’T: THE X-FILES

The X-Files

While we're on the topic of shows with cult followings, we would be amiss not to mention The X-Files. Mulder and Scully basically invented chemistry, the mythology was both preposterous and intriguing, the monster-of-the-week episodes often took on a comedic tone, and the show is now a pop culture touchstone.

In 2016, The X-Files was revived to mixed reviews, prompting plenty “Why X-Files doesn’t work today” pieces. As of now, there are no plans for season 12 and there really shouldn’t be any. We prefer to remember it the way it was back when our world wasn't what it is in “The Lost Art of Forehead Sweat”. The original show holds up and if it flew under your radar give it a go.

2 WANT: AGENT CARTER

Agent Carter

The cancelation of Agent Carter hit like a ton of bricks. The show about the beloved no-nonsense spy may not have hit the mainstream appeal ABC expected it to, but it certainly developed a devoted fandom. Agent Carter was one of the most thought-provoking, best written, and fun to watch superhero shows on TV -- something that ABC did not recognize.

But, with Marvel pushing for more female leads in Phase Four, this seems like the perfect time to bring back Peggy Carter. And not just a cameo in Captain Marvel, but back for real. According to showrunner Michele Fazekas the stage has already been set for season three. So, come on, Marvel. Make it happen.

1 DON’T: MINORITY REPORT

Ok, did anyone even want this show? The 2002 movie starring Tom Cruise was great and all, but it didn’t exactly demand a sequel. But, whether we wanted it or not, Fox decided to give us a sequel -- and a poor one at that. The show was a sequel in name only, as any deeper thematical connection was nowhere to be found.

Lacking the imagination, vision, and action that made the movie a success, Fox’s TV show was yet another by-the-numbers procedural but with more special effects. Minority Report was canceled after only ten episodes and we don’t ever want it to come back.
