Yebo. I don't have a problem with him as Danny Rand (I quite liked his cameo in Cage 2, seems his character has developed and matured a bit) but I cringe every time there's a fight scene. Even Bushmaster looked a lot more fluid and comfortable pulling off all those moves.
One of the drawbacks of watching a lot of kung fu movies is that you start to expect a certain level of competence, at the very least, when someone is a self-proclaimed master of martial arts.
