22. Iron Fist
Iron Fist was the last of the original batch of Marvel Netflix shows designed to set the stage for eventual team-up The Defenders. It was also the worst-received, with audiences not really taking to the more grounded interpretation of Danny Rand and the lore revolving around the Iron Fist. Its biggest issue was pacing, as it resulted in multiple episodes feeling drawn-out.
This was the first real stumble for the Netflix shows, which had been consistent up until this point. I personally don't feel like it was that big of a stumble, as the show was still highly entertaining and they tried to do some interesting things throughout that first season. Unfortunately, it just had a bit too much pressure on it as it was the last solo title prior to The Defenders, which also suffered from the same issues.
In Iron Fist's defense, the creative team actually listened to fans' concerns and produced a much stronger second season. History doesn't remind us of that enough, but season 2 was actually much tighter and more entertaining than a lot of the other installments in the Marvel Netflix shared universe. And we don't give Finn Jones enough credit for doing a great job as the title character.
