The Verge: "Fans feared the worst when the series was announced, and all their fears came true."
IGN: "Iron Fist is thus far the weakest of the Marvel-Netflix series."
Business Insider: "It doesn't live up to the quality of storytelling found in Daredevil, Jessica Jones, and Luke Cage. Plainly stated, Iron Fist is boring."
Collider: "What could have been the boldest series is instead the quietest. Seriously ... in the comics, the man gets his powers from punching a dragon in the heart, but that's withheld from us? If I wanted to focus more on reality I wouldn't spend so much time watching superhero TV."
Many publications specifically criticised the show's pacing problems, arguing that it takes a long time to get to the thrills and meat of the story. Others candidly claimed that it never even reached such heights...
Nerdist: "It would have been more of a thrill to see Iron Fist fully realized on Netflix if its 'slow burn' had ever caught fire; sadly, what it offers is the equivalent of struggling to strike a match."
Den of Geek: "I kept waiting for Iron Fist to kick it into another gear, and that sixth episode aside, it never quite did."

Many criticised the show's pacing – as it took too long to get to the more exciting stuff – while others said it just didn't have any thrills at all Netflix / YouTube
Variety: "It takes forever for anything to happen on Iron Fist, and as it stumbles along, the uninspired production design, unexceptional cinematography, and painful dialogue fail to distract the viewer from the overall lack of depth, detail, or momentum."
"Good luck, bingers: Getting through two episodes was a challenge."
Not all of the reviews were completely scathing however. Some publications praised the show's lightness in comparison to previous Netflix-Marvel series and championed Iron Fist's supporting cast...
Empire: "Iron Fist works some fantastical flavour into the MCU's down-to-earth Defenders nook, but it needs more proper kung-fu flair than showrunner Buck allows."

Some critics were impressed by the show's supporting cast however, particularly Jessica Henwick who plays Colleen WingMarvel Entertainment / Netflix
Yahoo: "For a show about a martial arts superhero, Iron Fist has a surprising lack of decent fight scenes. The action is mostly snatched moments, with the odd extended scene almost showing what the Iron Fist is really capable of... before stopping a little short."
"Colleen Wing (played by Jessica Henwick) manages to pull some of that back. But there's already been some criticism of how Danny treats her. At one point, he swaggers into her dojo and schools her on the martial arts she already knows. That's right – a white man explaining martial arts to an Asian woman. It's an awkward exchange, but I can't help thinking some critics are missing the point here... that's it's supposed to be awkward."
