11 Simple Fixes That Would Have Saved Marvel's Iron Fist
2. Fewer Episodes
Okay, so this one is perhaps the most implausible, because it's how the Netflix model works and was the plan for these shows from the very start, with only The Defenders getting a shorter run (8 episodes).
I'd say all the Netflix Marvel shows could do with being shorter, either in terms of the number of episodes in a season or how long each episode is, because 13 hours is a lot for these shows. Daredevil Season 2 and Luke Cage both suffered from the problem, and it's even more prevalent than ever before in Iron Fist, which stretches out such little story and character development over its 13 hour-long episodes.
Had it been shorter, with fewer episodes or shorter ones, then there'd definitely be a better pace to things, the story wouldn't feel quite as thin, and the series would feel tighter as a whole.
