1408 was good, but I also really liked "The Skeleton Key" and "Identity."
I almost didn't watch the Skeleton Key. My daughter watched it and said it wasn't any good. I'm SOOOO glad I decided to watch it and see for myself. I really liked it too.
Others I liked:
The Others
Population 436
Awake
The Orphanage (Foreign film, but oh so good)
The Eye (foreign one better, but the American one isn't bad either)
The Ring 1 and 2
The Last House on the Left (I think this was a remake)
The Haunting in Connecticut
Rose Red (4 plus hours, I believe it had been a mini series)
Saw movies (I think these get worse as they go though)
The Uninvited (though I loved the foreign version better)
Mr. Brooks
High Tension (this is foreign, but has been translated and spoken in English)
Frailty
Hard Candy
Harper's Island (this was a series, but was canceled after 1 season, it's a classic who done it)
The Fog
I know I could go on ad nauseum, but I'll stop here.
