Sadly, like all other scary movies, Poltergeist doesn't keep being scary. About the third time through, you're laughing at the crawling steak, which was the bit that really did it to me. Which is a shame, because the first time I saw it, that movie managed to scare me (and that's really, really hard.)

The only other movie that's ever scared me was The Haunting of Hill House- the original one. Those breathing doors? The whatever holding the girls hands in the dark? Holy crap. But even that one didn't hold up, alas.
