From the crazy parole officer to the way they bluntly telegraph every single thing that's going to happen to the absurd number of plot holes and mistakes to the bad sound editing (jump scares are fine, blasting my speakers into the next apartment is not) to the fact that the main character grew up in this house but doesn't know or recognize anything about it. But the most annoying thing of all is Lynn. The weird goth spunky nosey flighty girl whose only purpose in the film is to be irritating and frustrating.
