A Nightmare on Elm Street
Listen, we love the sequels to A Nightmare on Elm Street just as much as the next guy, but the 1980 version has all the rest beat. Wes Craven unleashed Freddy Krueger onto a generation that was, frankly, not prepared to be afraid of going to sleep. All other Freddy Krueger movies are great, don't get us wrong, but this one takes the cake.
