Hi! I am going to University in a couple of weeks and I'd like you to suggest a horror movie to watch together with my girlfriend (also coming). Our uni was built near a (!) cemetery and I would like something like that.. haunted campuses or perhaps a movie about a bunch of students killed while in campus or while studying or something ^^ thank you!

When I first read your question, I thought there must be loads. But when I thought about it, I couldn't think of many...
Suspiria, Scream 1 & 2, Urban Legend 1 & 2, Halloween H:20, and Cry Wolf spring to mind.

This one sounds kind of graphic...
