Wow what a great thread... I would have to say some of my faves are Halloween, Halloween H20, Paranormal Activity 1 and 2, Fright night, Salems Lot, The Shining, and pretty much anything else by Stephen King. Oh and Legion is a good movie... and I dont know if it is just me or what but I love The Grindhouse series of movies...
Can't wait to see Paranormal Activity 3... although my hubby says he is not going to go with me... trying to talk my sister and nephew into going with me.
Edited to add: I love Ghost Hunters and Paranormal Witness... watch these every week all year long lol... although my mom and dad live in a haunted house so I don't go to those anymore lol
