Cabin Fever
The first film Eli Roth ever directed might be his worst, the 2002 film Cabin Fever. Well, at least some people think that the movie is "good because it's bad." Cabin Fever is about a group of youngsters who are out on a vacation with one another, all while the group begins to contract a highly contagious and strange flesh-eating disease.
The Lords of Salem
The Salem Witch Trials might have been unfounded, but the revenge is very real in this 2012 film. A drug addict in recovery gets saved by a group of individuals who died in the witch trials themselves. It is unclear whether the protagonist is alive or dead throughout the course of the movie, but the heartfelt moments and genuinely beautiful cinematography help hold the whole thing together.
