It's not a horror movie, it's some sort of fun teen thriller-ish movie with some twisted scenarios but overall a quite simple script. It's not very scary, though there are a fez fun jump scares.
In this new psychological horror-thriller from Tate Taylor and Blumhouse, a lonely woman befriends a group of teenagers and decides to let them party at her house. Just when the kids think their luck couldn't get any better, things start happening that make them question the intention of their crazy host.
