8/10. It wasn't the best movie, but it is still one of my favorites. Although it is a horror movie, I didn't find it very scary except for a few moments and liked it because of the plot and story-telling technique. I like the concept of people being trapped somewhere and trying to get out, and the character of Jigsaw is my all-time favorite indirect serial killer. I like how they fill the time with flashbacks, with the flashbacks then switching to other characters' perspective. The plot twist at the end (I won't give away spoilers) about who Jigsaw was was good. Saw 2 was alrite; I didn't like Saw 3 and Saw 4.
