The fights in Iron Fist are all over the place. Some are pretty good, others are just awful. Also, it's obvious the lead didn't do a lot of the moves, the reason I say this is a ton of action scenes are shot in very low light, or he just happens to be wearing a hoodie, pulled up of course. There are so many moments when you can see it's clearly not him. Like, what? Super lame.
I had to double chell to make sure I actually knew what procedural refers to. Ha! Yeah, at the beginning of every episode someone turns up dead, and by the end they've caught the killer. I mean, there's other shit going on, but the investigation is the meat of the show.
