“Werewolf Castle” (** out of four) was a pretty generic medieval melodrama about a village boy (Peter Lofsgard) who goes along with a fearless group of knights (Greg Draven, Reece Connolly, and others) to end a werewolf invasion that threatens all of them but they find that it’s going to be a bloody fight to the death. Hardly the worst of its ilk but gory and one-note. At least it’s relatively brief at only an hour-and-a-half but it still runs out of energy pretty early.
