John Carpenter once called Prince of Darkness his most underrated film - an opinion I wholeheartedly endorse. While Carpenter is considered a master filmmaker now, many of his films either underperformed or outright bombed. John Carpenter movies like The Thing, Big Trouble in Little China or In the Mouth of Madness are considered genre classics, but they all flopped and met with mixed reviews upon release. The Thing, in particular, is now considered one of the best horror movies ever made despite being roundly panned in 1982.
