Only the french can open a movie with a vagina wide spread and not call it porn.
The french certainly have a different tolerance for nudity and sex as we all know but if it becomes pointless it just results in a cheap tool, as sex sells. I have to say though, that I didn't have the feeling at any time in the movie. All nudity scenes are there for a reason. While the style in which the film was shot in, is thrilling and you want to know what happens next, this has a small downside to it.
This movie has two possible endings, which you can see coming pretty early. So I was thinking either this will happen, or that. One of them then actually happened. So you have a 50/50 chance of being surprised. Normally I hate, when movies are to predictable, but in this case, it didn't actually hurt the film that much. The last scene though (without getting into spoilers) feels just ridiculous and it feels like, its simply there for pure shock value and nothing else to end the film with sort of a jump scare. Overall it's still an entertaining movie, nothing new, nothing to classy but you wont be bored for a minute and that also matters a lot.
