Oh man it's so good... There is something about the "fight scenes" (more like scuffles) that are some of the most realistic I've ever seen in a movie.
There's one where the guy comes running at full speed from off screen and full-on dropkicks another dude out of nowhere that made me literally LOL. I had to rewind the scene to watch it multiple times, it's just so good I can't even explain it.
Some amazing long one-shots too
