Laughably bad and definitely stupid. Obviously 1973 special effects limit what they can do with the werewolf. But between Dean Stockwell's over-the-top performance, and the ridiculous dialogue (plenty of wolf and dog puns), this sinks below "so bad it's funny" and eventually becomes just bad. Worth watching for a few laughs in the middle part, and it helps if you have a "bad movie" host helping you through.
