"The look of this movie is striking, and even lacking the nudity and gore of the later films in the Daninsky cycle, this still generates a marvelous ambiance of menace. The filmmakers make good use of the locations, which are richly decorated by the prop department, and they cover for any deficiencies with a striking use of colored lighting. The whole thing plays as if Terence Fisher and Mario Bava had had their genes spliced and their mutant progeny had turned its attention on the Universal-style monster rally... Even given the movie's reliance on werewolf action--a given in any Naschy werewolf picture--there's an otherness to this movie that eludes most of Naschy's other films and turns the "blender" quality of its construction into a kind of dream logic." - Christianne Benedict, Krell Laboratories
