How bad is it? Bottom-tier 1970's soft-core.
Should you see it? I can't imagine why you should.
This is an obvious remake of "Little Shop of Horrors" that escapes legal action by adding sex subplots and removing what wit or charm the original may have had. A 40 year-old living with his mother is unable to get a girlfriend, so he becomes a peeping Tom. This means that our main character does little but stare and leer while the cameraman shoots mostly unattractive people having sex. One couple is in a park, but manage to be in the same sex act every time they're peeped upon, supposedly over the course of days. The guy then buys a plant that eats people and his mother gets dispatched about half-way through the film - and she's such a harridan that you'll be glad and feel that her son must be of two minds about it - and he then becomes attached to the plant and recruits more victims. The director gave himself a small role as a detective. Porn star Rene Bond is the only recognizable, um, face. The jokes, such as they are, fall flat.
