Review of Queens of Evil

It coud have been a good short film, or an acceptable medium-length film, but it is one of the most boring movies I've ever seen. Nothing happens in the movie before the last 7 minutes. There is no plot, no tension, no pace, no mood, it is not haunting, or trippy, or visually mesmerezing, or atmospheric. Nothing at all. And I am really into slow and long movies. I love low budget movies from the 70s, but I can not positively value a movie for having only a good final seven minutes.
