Formulaic garbage right down to the "twist" ending. You can pretty much see everything coming a mile away. The film establishes specific rules for the monster and then blatantly violates them, basically laughing in the audiences face. The plot is incredibly basic, main character see's a monster, main character can't understand why the things she's saying are crazy. Etc etc. Please save yourself the time an do something else. Like watch paint dry, or spin in circles. Oh and it has the generic horror movie ending. You know the one. No matter what, even if the protagonist does everything right they lose. Doesn't matter if they grew as a character, or learned a lesson. It's always the same ending.
