Looks and feels as if made by teenagers raised on MTV and video games, and gets more and more ridiculous as it goes on. As a political allegory for France c.2004-2007 (the Paris riots, the hijab ban, election of Sarkozy, etc.) it's about as subtle as Animal Farm. Extremist cinema has done better.
Not something really special. Just a bunch of crazy incest lovers who by the way are neo-nazis and cannibals are having fun in their little cottage romantique. If you want blood , extremity and some cheap fun you can gladly watch it , if not , better stay away.
Terribly misogyny and hate masquerading as a horror film, but where's the horror? Instead of suspense or actual horror this movie is concerned with gore, bad shaky cam, and idiotic characters who don't matter at all. It's also very concerned with copying The Texas Chain Saw Massacre verbatim, but in French, so it must be different, no?
