My dislike of Iron Fist came down a few notches once I reconciled the fact that this isn't the comic IF I remember. Watching the Defenders it came to me that being the supreme martial arts master isn't the niche for IF. That is DD's role. Watching DD beat the shit out of most everyone, he is clearly being shown to own the super martial artist slot. I view Danny Rand now as a rich kid with a "magic fist" who can break almost anything when he uses it but it has a pretty long cooldown to balance it. Once I changed my view, I became ok with IF as a character. Pretty well satisfied with the Defenders series. Enjoyed it a lot.
