I think they just gathered actors in a room and said: "You've seen horror movies, right? So let's film a horror. We don't have a script, though, but you'll figure something out"
I would not even call it a movie, it's just a compilation of familiar scenes from other horrors, without any logical connection.
Even jumpscares don't work, they are either cut too early, or ruined by PlayStation 2 graphics.
You don't really expect well-written characters or logic from a horror, but you expect something. Just give me some vague explanation about "evil" possessing the house and make all the characters dumb, that's good enough for me, but in this movie things just happen. Actions and knowledge of the characters don't affect anything.
It is hard to explain, but this movie feels like something generated by a neural network. It feels familiar, and you can recognize some parts, but it just doesn't make any sense in general
