Hands down--at home. Without sounding like a complete Crabby Patty, there are too many people who chat or make other noises during the movie, and for some crazy reason, these folks always seem to be sitting in front of me, beside me, or just in back of me. My husband would like to go out to a movie sometime, though, so maybe we can swing a matinee. It is fun to watch a horror movie with a big audience though. We all scream at the same time, then laugh afterwards!
