Try as you might, there is no way to watch every horror movie ever made in the month of October, no matter what online DVD rental site you use. There are just too many options available. Picking the right Halloween movie for yourself or for a party is important, which is why we've compiled a list of the 20 best horror movies. Also, since Halloween movies come in a wide variety, we've separated them into different categories and picked a winner for each category.
First up: Best Classic Horror Movie, Best Alien Movie, Best Vampire Movie, Best Werewolf Movie and Best Zombie Movie.
