It is a stretch at times but his gun handling is believable.
He is a 3 gun shooter and trains
Well, it's the movies.
I think falling 1 story and landing on your back is going to put you out of action longer than it did for him.
But it least they didn't do that slow down time crap. Like as if he's 10 times faster than everyone.
He was fast, but a bit more believable.
