There was an interview with Finn Jones I saw yesterday about the fights, allegedly he was cast 3 weeks before filming began and on shooting days was given minimal time to practice the fights and this is why the fights sucked (though keep in mind this is the same guy who 9 days ago was telling people the show would be taken badly because Donald Trump). Now maybe that's true, maybe it isn't. Frankly I don't really care about the why, it just emphasises to me that they needed to include the mask to make it easier to cut the stunt guy in so we don't end up with fight sequences that have more cuts than an old man jumping a fence in Taken (seriously, rewatch the hospital fight. 56 ****ing cuts in a 30 second scene).
Daredevil had great fight scenes, and not to belittle Charlie Cox's contribution but I'm sure having the hero be masked played no small part in how well those came out, between powers and personalities of the characters involved Jessica Jones and Luke Cage get something of a pass for fight scenes consisting of Punch - Cut to guy flying across the room, but this was the one that needed the fights to be top notch and it failed miserably, I can only hope come Defenders time they can really tailor the fight scenes to the characters and do it right.
