Of the 8 reviews until now, there are 4 with a raving score of 10. I hardly can believe that they watched the same movie as I did. In my opinion this is a totally failed wannabe thriller-horror flick, that I only sat through because I (stupidly) paid 5 euro to stream it.
Maybe the premise has some potential (two couples have booked an isolated cottage in the desert, only to find that there's already a weird older couple in the house that has no intention whatsoever to make way, but instead starts to behave more and more creepy), but out of some misguided arty whim the director decided to mix up the timelines of the individual couples arriving at the house, as well as that of the police officers that later arrive. This makes the already flimsy story completely chaotic and a tiresome watch.
Add to this that all characters (except the female officer) are extremely unsympathetic and even unpleasant to look at, that the dialogues are cringing, that the setting is limited to the uninspiring interior of the cheap looking cottage, and that the acting of the whole cast is below every reasonable par. Gradually the story derails into some kind of bloody grand guignol theater, but unfortunately without the needed tongue-in-cheekness that maybe could have saved this ill-fated project. Please don't waste money on this!
