Where is the Exorcist when Regan turned her head all the way around?
Where is original Night of the Living Dead when the girl rose and bit her mother
Where is the 1950s War of The Worlds when the Martian put its hand on the heroine's shoulder
Where is Bambi when the hunter shot ...
Karloff's Frankenstein when the monster threw drowned the little girl. They didn't show it (if I recall) but the inference was scary.
