The Marvel name is synonymous with high-quality content from comic books to blockbuster feature films. Recently, Marvel has produced a number of critically acclaimed television shows to coincide with the Phase Four chapter of storytelling. However, not all Marvel-produced shows see the same level of critical success. Unfortunately, because Marvel sets such a high bar for the quality of its content, not all its TV shows is able to clear it.

The review analytics website Metacritic aggregates critic and user reviews to create a fair numerical ranking of popular content.

10 What If...? Is For Marvel Faithful Only

Metacritic Score: 69

The multiverse as shown in What If...?

Marvel's What If...? is an animated series whose first season premiered on Disney+. The show plays out hypothetical storylines outside the official MCU canon, exploring ideas such as "What If...Ultron Won" and "What If...Thor Was An Only Child."

While What If...? garnered mostly positive reviews, the niche storytelling limited viewership to the Marvel faithful as many of the storylines required prior story knowledge to enjoy. Still, the show received mostly good attention and fans eagerly await its second season, set to hit the small screen in 2023.

9 Runaways Couldn't Find A Home With Audiences

Metacritic Score: 68

2017 saw the release of Marvel's Runaways on Hulu. The series was based on the characters from the Runaways series of comic books and followed six teenagers coming to grips with their supernatural powers. Not only do the young heroes have to navigate their teenage lives on top of their newfound identities, but they were also forced to face off against a group of villains known as The Pride composed of their parents.

Runaways gathered some positive reviews and aired for three seasons on Hulu. However, the series struggled to find a consistent tone and strike a balance between its storylines of teen drama and superhero struggle.

8 Cloak & Dagger Remained In The Shadows

Metacritic Score: 68

Tyrone and Tandy stay together in Cloak and Dagger

Marvel's Cloak & Dagger was another YA-skewed offering from Marvel that originally premiered on Freeform in 2018. The series followed two teenagers from very different social spheres whose lives are forever entwined after a childhood tragedy. Both are granted superpowers by the event, and the two teens soon learn that they are stronger when they utilize their powers together.

While Cloak & Dagger received many positive reviews, it ultimately was unable to find a footing in its genre. The tale of star-crossed superhero lovers was canceled by Freeform after only two seasons.

7 She-Hulk: Attorney At Law Was A Divisive Case For Audiences

Metacritic Score: 67

She-Hulk: Tatiana Maslany's She-Hulk breaks into the show's writers room, which is covered with storyboards and concept art.

She-Hulk: Attorney At Law is the last of Marvel's Phase Four slate of programs on Disney+. The miniseries stars Tatiana Maslany as the titular hero and lawyer also known as Jennifer Walters. The nine-episode series also saw the return of Charlie Cox reprising his role as Matt Murdock, as one of its many big-name cameos.

While the majority of critical reviews were positive, audiences were quick to call out what they perceived as poor special effects featured in the series. She-Hulk was created as a one-off miniseries and Jennifer Walter's future in the MCU is currently unknown, however many fans are hoping to see her pop up in Marvel's Phase Five entries.

6 Hawkeye Wasn't A Bullseye

Metacritic Score: 66

Hawkeye on Disney+ made a splash with fans for its star-powered cast. The series followed mainstay avenger Hawkeye (played by Jeremy Renner) as he took fellow archer Kate Bishop (Hailee Steinfeld) under his wing. The miniseries even boasted a surprise cameo from a big-name MCU star in its six-episode run.

Hawkeye saw both positive and mixed reviews, with particular praise for the cast. While critics had no outright complaints about the one-off series, the show also failed to set itself apart from the rest of the MCU fare and holds a middling rank amongst Marvel's television offerings.

5 The Defenders Was Less Than The Sum Of Its Parts

Metacritic Score: 63

Jessica Jones, Iron Fist, Daredevil and Luke Cage in an elevator in The Defenders

Before the launch of Disney+, many of Marvel's series called Netflix home. The service hosted heroes such as Daredevil, Jessica Jones, Luke Cage, and Iron Fist. Their series The Defenders saw a cross-over of these four shows with the heroes coming together to fight injustice in New York City.

Despite the ambition of the crossover, Defenders was far from an all-star reunion. The quality of the original shows varied quite a bit, and the four heroes didn't always gel as a team. What's more, despite being an event miniseries, many decried the story's incredibly slow pace and lack of action.

4 The Punisher Failed To Bring Justice

Metacritic Score: 55

Frank Castle wearing his skull symbol in The Punisher series

2017's The Punisher aired on Netflix as a spin-off of Daredevil, a Marvel show that had been a hit for the streaming service. The Punisher follows Frank Castle (played by Jon Bernthal), a former marine turned vigilante seeking bloody revenge for the murder of his family. The Punisher offered a gritty take on the Marvel superhero world, with Bernthal's Frank Castle operating from a place of violence and anger.

Despite this, The Punisher earned largely mixed reviews from critics. TV writers bemoaned the lack of pacing and general banality of the plot and structure, combined with misgivings regarding the show's glorification of gun violence. The Punisher was canceled after two seasons, but it has been heavily rumored that fans may see the character reappear in Marvel's Phase Five content release.

3 3) Helstrom Had Serially Bad Luck

Metacritic Score: 40

Ana and Daemon in Helstrom TV show

Helstrom was originally conceived to be the first entry in Marvel Television's Adventure into Fear franchise. The slate of television shows was to be part of the official MCU canon and involve other series such as Ghost Rider and air on Hulu and ABC.

Unfortunately, none of that came to pass and the mediocre comic adaptation about siblings hunting serial killers failed to gain critical or commercial interest. Helstrom's middling reviews, combined with Marvel Televisions' merger with Marvel Studios, led to a swift cancelation for the series and an end to the adventures of Daimon and Ana.

2 Iron Fist Couldn't Punch Through The Competition

Metacritic Score: 37

Finn Jones Iron Fist Netflix

Iron Fist was one of Netflix's quartet of superhero programming that culminated in The Defender's event series. Finn Jones led the series as Danny Rand, better known as the Iron Fist. Danny is a bored rich kid who after misadventure stumbles upon the ancient powers of the Iron Fist, which makes him a martial arts expert.

Iron Fist received an outpouring of less-than-positive reviews, with critics pointing to the show's mediocre plot and dull performance from leading man Jones. Despite this, the show was renewed for an even more lackluster second season before being canceled entirely.

1 Inhumans Was Out Of This World Bad

Metacritic Score: 27

An image of the cast of Marvel's Inhumans.

The ABC network had seen success with its Marvel Television series Agents of SHIELD and was setting up another big-budget superhero success when it developed Inhumans. The show followed the Inhumans, an alien royal family with spectacular abilities who find themselves on Earth after a coup in their home world.

Despite the money ABC put into Inhumans, it had an overwhelmingly negative reception. The character's unusual powers didn't always translate, and critics pointed to consistently poor writing and production execution. Even though the series had a planned multi-season arc, it was sent packing by the network after just one.
