How bad is it? It's the worst Andy Milligan film, so the worst of the worst.
Should you see it? NO! I HATE THIS FILM.
In one of the first posts on this blog, I said I wasn't going to review Andy Milligan films and this film was the main reason why; this is I think the seventh of his now reviewed here. One of five films Milligan shot while in England, this takes place in a gloomy old house a long time ago (people wear period costumes not identifiable to era, though you can see light switches on the walls and a neon sign in one shot). A woman brings her husband home to meet her weird family and tries to hide the fact that she's pregnant. The sister whips and beats her imbecile brother and brings home a collection of rats which get tortured and killed: this is not faked. In the last few minutes, the titular werewolf turns out to be the brother. The rats - actually mice - were added three years after most of the film was shot, to capitalize on the surprise hits "Willard" and "Ben," which happen to be the names of two of the rats in this film. Like all of Milligan's films, this was shot in 16 mm, there's problems with sound pick up, action scenes are underlit, most of the film is just talking shot in wide angle, but the acting is better than usual for his films. I find it unwatchable... and I've seen it twice.
