Just kidding, didn't find that suspenseful at all. Rear Window, perhaps? Or What Lies Beneath? I saw that movie when I was about nine and it scarred me for the next couple of months...
Pulp Fiction had me on the edge of my seat the first time I watched it. Especially the basement scene. HOLY SHIT! I was like a little kid wanting to close my eyes.
I was exhausted after watching The Grudge (American version) I spent a lot of energy tightly gripping the arms of the cinema seat. My wife who loves horror thought it was hilarious.
