Bad News: Based on Rotten Tomatoes scores right now, Marvel's Iron Fist Netflix series looks to be a turd in the punch bowl:

Good News: That is only based on 14 total reviews so far, reviewers have only been allowed to see the first 6 episodes, and some of the reviews seemed to focus too much on the white-washing aspect in their opinions rather than whether the series was actually good or not.
Trust me, I understand the white-washing argument, and get where they are coming from. However, that fact shouldn't affect how good the series is or not. Also, I've never been a fan of sites like rotten tomatoes rating TV shows based off of a limited number of episodes. Shoot, sometimes, they are just based off the first episode. Therefore, even if the first 6 episodes suck, in a 13-episode series, that leaves plenty of time to turn things around.
