That's funny, cause for me its the opposite. I find it much harder to be scared in a movie theater full of other people than just watching something by myself, alone at night.
Paranormal Activity was a blast to watch in the theater because everyone was freaking out. At one point, a woman started crying - CRYING - in fear. But it was distracting. My mind kept floating to "man, the filmmakers must love going to showings of their movie to soak up this reaction."
So in that sense, I'm the same way, Bullet. But right now I'm at my parents' house all alone except for 2 dogs. It's in the middle of nowhere, on a lake, and they have an awesome entertainment center. So I'm in a good position to scare myself with movies this week.
