Though Marvel's Inhumans hasn't yet had its official series premiere -- that's this Friday night on ABC -- there are already plenty of opinions of the show, due to both the first episodes debuting earlier this month in IMAX theaters, along with poor word of mouth from the show's promotional material and negative reviews.

There's already been some speculation as to whether or not Inhumans might make it to a second season on ABC, and while that's still very much up in the air -- again, it hasn't yet premiered on TV-- showrunner Scott Buck has made it clear he doesn't view the first season as one-and-done. In an interview with Collider, Buck said he's got ideas for a season two -- and beyond -- if he and the rest of the show's team gets the chance.

"We have ideas," Buck told Collider. "We know our starting point for Season 2, but we don’t know if there will be a Season 2. Hopefully, there will be a Season 2. If so, we know where we’re gonna start, and we’ll very gratefully gear up and get to work."

In fact, there's at least a general plan for the first three seasons, with the show continuing to follow the Inhumans royal family.

"We generally know where the first three seasons could go," Buck said. "What’s fun about the show is that it will basically always be a show about family, so there’s always going to be places to take these characters."

Inhumans has had an uphill climb since early in its existence -- first announced as a Marvel Studios film in 2014, the plan shifted to a live-action TV series announced in November 2016. The show has received criticism for its costumes and wigs as seen in early promotional images, and currently has a 29 ("generally unfavorable reviews") rating on review-aggregating side Metacritic. Yet Marvel has shown strong confidence in the characters, introduced by comics legends Stan Lee and Jack Kirby in 1965, in recent years, having also greatly increased their prominence in its publishing line.

Earlier this week, a report from Variety stated that the upcoming fifth season of Marvel's Agents of S.H.I.E.L.D. was ordered as a mandate from corporate owner Disney to ABC, despite some in the network wishing to cancel the series.

Starring Anson Mount as Black Bolt, Serinda Swan as Medusa and Iwan Rheon as Maximus, Marvel's Inhumans starts it eight-episode run this Friday, Sept. 29 on ABC.
