I loved that movie. I'm guessing you're not talking about the 1971 version. Or if you are, then maybe you had to be there.

I liked the original version. I'd put it up there with One Flew Over The Cuckoo's Nest on the list of best adaptations. But I've seen some god awful remakes, most notably the recent miniseries with Benjamin Bratt.

Haven't read the book, but I loved the movie. It's the only movie ever to succeed at giving me nightmares.
