Are you KIDDING me?! I mean, I thought it was a good movie, and it certainly succeeded in scaring the living hell out of me, but to watch it OVER AND OVER AGAIN because you ENJOY it?! That's crazy. I could see it *maybe* once a year, tops. After which, I'd need a few weeks to recover...
But by all means, whip out the popcorn and go for it, if that's what you're into!
