Saw is much more than gore. They are psychological thrillers.
Shame on you.
As for torture scenes, I cannot handle rape scenes. Oddly, one of my favorite movies has a 10-minute (ten full minutes, one unbroken shot) rape scene, but I think the fact that it's anal and not vaginal (thus making it more of a power thing and less of a power over women thing) is what makes it tolerable for me. And the movie is brilliant.
