Could a very mature 13 year old handle Saw (movie)?

I'm 13 and am interested in watching Saw. I've seen other scary movies, like Blair Witch, The Exorcist, and The Birds. I've also played rated M games, such as Left 4 Dead, all the CoD games, Fallout 3, Bioshock, and a little bit GTA 4. I really want to watch this movie, but I don't know whether I'll puke or something.
