Naturally, everyone who helped cobble together the 101 best horror films of all time like scary movies.

If you can count on the movies for anything, it’s that there seems to be an exhaustible supply of scares. Then, just when you think it’s safe to go back to the theater, something else comes along that reminds us that there are always new ways to come us screaming in the dark.
