Well, I saw it last night, and I have to admit, it is pretty scary.
Here is a link with info on the original movies, and the american remake. It has some spoilers, though, so watch out.
I saw the movie about a week ago myself and it wasn't bad. I did have to problems with it (NO SPOILERS!) ...
1.) It was pretty darn long.
2.) The lead male was supsoe to be a counter culture type yet the only thing that he had to prove it was his locker stickers (Refused, Pennywise, etc ...).
