Something Wicked This Way Comes is a good one. Not a big fan of Killer Klowns - it was funny though. Never seen Children Shouldn't Play With Dead Things.
Watched The Strangers last night. Not bad. Excellent surround mixing!! The story was relatively predictable, but it managed to generate a fair amount of tension.
I pulled out a few that we intend to watch: The Orphanage (well done, solid thriller, very little blood), The Thing ('82), Corpse Bride, maybe The Grudge, Sean of the Dead, Hot Fuzz, and definitely Se7en.
