The Little Girl Who Lives Down the Lane
I don't know how much other people will enjoy this one actually (I've shown it to four or five people, and none of them cared for it) but I thought it was a really interesting little mystery film, with a very unique atmosphere. One of my favorites.

Fright Night
One of the best horror films ever, in my opinion. It's just a really fun film, that's a total blast to watch. Roddy Mcdowall is also outstanding in this.
