Creepiest would have to be in Shallow Grave when the one roommate starts hiding out in the attic and drills small holes in the ceiling so he can look down into the apartment and see what everyone is doing. Or maybe the part when they are in the woods chopping up the dead roommate.

Cringeworthy would be the scene in Gangster #1 when he is beating that guy to death in his house that goes on for what feels like half an hour. Its not so bad at first but it just keeps going.
