No. 4: SAW 2
SAW 2 - This movie wasn't scary but I'm putting it here because this is the only movie that I though I was gonna have to walk out of.
Two words: "needle pit". I just couldn't do it.
When they pulled the bed away and I saw thousands of needles in the pit, my heart stopped. I thought "this is not gonna end well for me".
I made it through, but to this day if I watch it on TV or DVD I make myself scarce during that scene. No Thanks!
