Have you seen Serial Lover? Also a french movie, also with quite the dark humor included. And I would argue a lot better than the movie we have here. Which does not mean I was not entertained by that (remember it is a movie, I don't condone any of the behaviour shown here, especially the sending of genital pictures ... and the reaction most display to it - this is not funny, period).
Having said all that, just take it with a grain of salt, this is horror mixed with comedy. A lot of violence, but no nudity (in case you were wondering). Though the movie is not worse or better for that in my humble opinion. You may feel different - especially considering the beautiful people who assembled for this. B-movie flair and charme ... might be enough or not, depending on your sense of humor.
