Saw IV
the games have just begun
As I am a very very.... very squeamish person, I tend to just look away during any of the actual trap scenes; I have to admit that I really like these movies for the story, it's kind of fun to figure it all out as you go along, since it's so convoluted
I've been watching one every night, might actually watch Saw V now as well, even though it's almost 3am
