More than any other film genre, horror is defined, to some extent, by its sequels. In the past several years alone, a half-dozen major horror franchises, including Child's Play and Pet Semetary, welcomed new entries to the big screen. Because horror films are relatively inexpensive to produce and come with some degree of guaranteed success, sequels are a perfect way to keep a familiar franchise afloat by giving fans more of what they already like. Despite that, one of the most acclaimed horror movies in recent memory, 2012's The Cabin in the Woods, still hasn't had a sequel.
