"Flaenset" is a tedious, pointless little splatter flick which begins with a ridiculous conceit and then does nothing with it.
If you've ever seen a Danish movie you will probably recognise Thomas Bo Larsen. He has to be one of the better actors from that part of Scandinavia. So what is he doing in this movie?
He plays a man who witnesses his wife cheating on him with another man. The sex scene is done so graphically it becomes stupid, but not as stupid as Larsen's response. Yes, he turns into a "psychopathic serial killer", who even dabbles in cannibalism!
Are we supposed to believe that he was a perfectly nice guy before his wife did the dirty on him - and the shock from that gave him a craving for human flesh? How does that work?
He kidnaps some poor lady and makes her come with him on a killing spree.
I just did not care about this movie. It's pretty violent, sure, and graphic in its sex scenes. But it's also boring, and has no sense of narrative cohesion.
