I was really surprised when I watched this flick, I thought I would get bored to death, but this flick made me more and more involved in its sleazy plot. Lots of nudity and an entire set of perverted characters makes you wonder who the real killer is till the very end. I don't even remember how I got my hands on this flick, but I gotta say, I'm glad I did. Good soundtrack and nice performances too, though I have to admit I wasn't familiar with any of those actors. And (not really a spoiler by the way,I'm not saying who the killer is, it's just a comment about one of the scenes). SPOILER: I really loved the killer insanely sucking on breasts on the posters plastered all over his room. Delightfully fascinating and creepy.

The First time my friends and In watched He Kills Night After Night we had no idea what was going on. There is a bit of a mystery involved as to the true identity he who kills night after night. Every time we watched it after we knew exactly what was going on, and the movie just got better and better. I have to admit that i love this movie. It has some of the best dialog, and one liners. When we watch it now, we just giggle at it. The best part about the whole thing is when the plot elements finally come together it goes so far over the top that your jaw just drops. It tries to be a morality tale against the loose sexual climate of swinging seventies London. So give it credit for at least trying to have an ultimate point. That might just be an excuse to have a slasher movie, like any reaction will do to justify a good horror/mystery movie. The bad guys always feels justified in his motives, no matter how far out they may be. So that being said, I would recommend this movie to anyone. not everyone might understand it at first, but if you watch it a few times, it gets better and better.

A rash of brutal slayings leads Scotland Yard investigators to a pompous mod hipster, but the true culprit may be a lot closer to home than anyone realizes. This glowering little slasher genre prototype is a leering and perverse cocktail of sexual depravity, and may be of more than just passing interest to fans of both gialli and lurid trash cinema. Briskly paced compared to many contemporaneous British thrillers, this one surprises with steady direction, credible performances, and occasional off-kilter camera-work which enhances the delirium of the grisly goings-on. One standout flaw is the film's weak conclusion...though not unsatisfactory, it's a tad anti-climatic and hurried. Pardonable inconsistencies aside, a very worthwhile watch. 6.5/10

This movie had some interesting ideas and twists. I thought everyone in the film was messed up and I wouldn't have minded if any of the suspects were "the one." Each suspect had his own perverted/sexist ideas about women so I honestly didn't know which creep did the murders.A sidenote: There is a striptease scene in the movie that I have seen in another horror movie. This exact striptease footage is from another movie, but I don't remember which one.All in all, it is an interesting film and I think it pushes some boundaries moreso than most other sex-maniac focused horror movies. There are parts of this movie (basically all the parts that took place in that little room with all the pictures) that were actually disturbing to me as a woman. Nearly all other sex maniac horror movies do not step over this line of discomfort. I say a movie that can cause discomfort like this is a successful movie in some ways. I give it a 5/10.
