Slant Magazine concludes, "Lee’s performance pushes The Devil Rides Out from being merely one of Hammer’s better films into the territory of horror classic." Variety calls it "a suspenseful pic, with several tough highlights, and gets major effect by playing the subject dead straight and getting similar serious performances from his capable cast."
Empire Online says Lee gives "a memorable and unusual performance as the sorcerer, the hero of the film." Time Out says, "Over the years, this film's reputation has grown enormously, and its cult status must be as high as any horror movie." Rotten Tomatoes has a critics' score of 94%.
