The alley scene with 2 guys why the sloooooo kick back lol

So I do like this movie and there are a lot of things that are wrong and not so great BUT what always bugged me was the alley scene with the 2 guys

why did the film makers decided when she uses SUPER blow on that guy and he goes flying back FAST and normal speed but then the guy she kicks they have him go back soooo slow that it looks total stupid?

its not like they even went for a slow motion look lol



another part which I do not understand why they did not just reshoot it was where shes flying to the mountain as its just appeared, we get the blue screen shots of her flying fast then it goes to where she is on wires and flying toward and above the camera with people infront of the camera pointing at the mountain and who ever was controlling the flying rig messed up because as well as flying forward toward the camera back half of her body turns to the left so shes wonky flying forward :/

they should have just reshot that as it looks way too bad
