It’s unusual to encounter a negative assessment of this movie, but there’s a delicate distinction between unintentionally amusing horror films and genuinely funny ones. This one lands firmly on the wrong side. The story revolves around three magicians competing after they gather at the gothic castle belonging to one of them. What follows is an attempt at humor that makes even Adam Sandler's least impressive performances seem comparable to those of Oscar Wilde. While some viewers might find it entertaining, the absence of actual laughs renders the experience quite uncomfortable. Roger Corman directed a single exceptional film, "Frankenstein Unbound," but his tendency toward low budgets and careless scripts has produced works akin to those of Ed Wood. People generally avoid criticizing this fact, though, because Corman is celebrated for providing opportunities for aspiring actors and consistently turning a profit. It's easy to generate revenue from cheaply made movies. “The Raven” includes Boris Karloff, Vincent Price, and Peter Lorre, but their performances are disappointing. They act in an exaggerated style and fail to elicit any amusement. A young and athletic Jack Nicholson appears briefly, offering no indication of his future Academy Award wins. Corman’s direction is unremarkable, and Richard Matheson's screenplay feels as though it was written during filming. I suggest skipping "The Raven."
