This review is a f*cking piece of crap. There's a lot of martial art fighting but none of its bloody, sometimes you can see the skeleton to see the bone fracture. Two girls kiss in a club with no nudity. Also there are only three uses of the f-word. Easily PG-13 material. However the bad is that all Chinese and black characters are shown as crime lords or gangsters, which is bad. Also the characters aren't properly introduced and the story is never explained properly so it is hard to follow. Overall a really fun movie that I recommend.
It really isn't very bad considering most R Rated action movies out there, but there are still some very graphic and brutal fight scenes which contain bone crunching sound effects. Also, there is a some strong language, mostly in rap music lyrics. There is some extremely brief nudity at the begining and some drug references. That's it.
