i cant believe people actually pay money for this crap... theres only like 3 films that are worth seeing in a theater that scary
1. The Exorcist
2. The Decent
3. Dawn of the Dead / Event Horizon
I personally believe that movies like Paranormal Activity are more scary than what's above. To me, making the audience think and imagine the horror themselves, as opposed to outright showing it is more psychologically compelling. It's also has a more lasting effect too, since you then carry what you imagined in the theaters back home with you.
