Personally I love horror comedy. I just find it so re watchable. Other then that I really enjoy zombie movies and find paranormal likely the spookiest. I bet you can guess how many times I've seen return of the living dead, lol.

Least favorite is likely revenge films or anything shocky just to shock (like the terrifier films). I also really don't like nic cage. He's ostensibly too over the top for me.
