I loved how in Carnival if you could time it just right you could keep shooting the lowest bear in the bonus level and just keep him going back and forth like 20 times. Also the elusive diamond that would appear in a dropped apple in Mr. Do. I think I only had it happen twice ever in what seemed like thousands of games.
It could just be that I first watched it when I was pretty young, but The Changeling from 1980 with George C. Scott is a pretty good atmospheric horror. No real gore or even deaths to speak of, but a good creepy ghost story nonetheless.
