I am a big fan of Paranormal Activity 1 and 2.
The Saw series was pretty good, I haven't seen the last one out, but the rest of them have been good so I'm sure it's a good bet.
Rob Zombie has a knack for directing some interesting movies:
I really enjoyed House of 1000 corpses and The Devil's Rejects, but I am a fan of something different.
And, for the attempt, I did enjoy the new Nightmare On Elm Street. I have been a fan of Jackie Earle Haley since he was in the original Bad News Bears
I hope these are some good ones for you.. there are a ton of great horror movies out there, but these are the newest ones that are sticking out in my head at the moment.
Scary movie watching!
