Just like the 90s PG13 movies; it is what it is.
GOOD: Fun martial arts scenes, brutal Rated R fatalities, awesome combat arenas or "levels" if you will, most of the acting was better than expected and much better than previous movies... ASIAN ACTORS! Oh, and Kano is perfect and steals most scenes
BAD: Moments of subpar CGI (Raiden's eyes remind me of the awful Green Lantern mask), plot is not very coherent and is trying to do too much and doesn't do enough, some scenes are bit lacking and could've been fixed with different editing.
UGLY: Kabal is awful. Bad writing, bad delivery, and just trashy
If you played the games at all, you should enjoy this movie. I enjoy it and will watch more than once. Hoping they have a polished sequel...
