One in my opinion would be The Exorcist of Emily Rose. It's basically based on a true story about this girl, named Emily Rose (That was a tough guess) that's posessed by the devil (apparantly) and goes through a ton of medical stuff, as well as court appearances. I went to the theatre to watch it. I got a kick out of it.

I also remember watching The Ring the first time...freaky - but now it's a comedy to me.
