For once the good reviews and ratings are real! Like many here, you check on the ratings and see that the 7.5/10 is a handful of low ratings, then a disproportionate number of 10/10 pushing the average up. These are clearly fake, friends of the director etc., and experience tells you you're looking at a dead horse being flogged.
But this is really a decent and original thriller/shocker. Though the ingredients don't look particularly appetising (think Drive like cinematography though not quite as stylish, American Psycho style humour and violence, Scream like Hollywood beautiful people but not that beautiful, and a bit of Eli Roth, plus mostly really unlikable characters) but somehow it works.
Give it a go!
