The scheme of a couple abducted by a group of psychopaths reminds me OPEN SEASON and PENTHOUSE, in a disturbing, nasty, insane atmosphere, where audiences feel dizzy nearly all long the movie. It is not always very clear and fully explained, you have to watch and listen it very closely. Not for all audiences, not for Hollywood crap films fans. Don't watch it with your parents in law around the poultry, this is not entertainment. This is actually a complex psychological study which maybe needs to be seen several times. This is not a gore, horror movie, nor a thriller, perhaps more a bloody and brutal drama. There is also a bit of Michael Haneke's FUNNY GAMES, but just a bit.
