No. 3: Poltergeist
Poltergeist - Geez what a frightening movie to watch as a kid. It scared me for sure... however, and you may laugh, but the thing I found most frightening about that movie... was the little old lady, Tangina, that came to help them rescue Carol Ann. Irrational maybe, but as a kid I thought she was the one that caused all the problems in the first place. Truly frightening experience for me.
