This is one of those movies that had everything to be very good, but ends up disappointing the viewer. The beginning and introduction of the plot is very efficient and exciting, leaving the audience wanting to find out what's going to happen. However, when the process of concluding the plot begins, the movie leaves a lot to be desired. Several inconsistencies and unexplained things are left behind. It's not a plot hole that leaves the audience wanting more, but a significant inconsistency that ends up damaging the viewer's experience. Some say that the film was intended as a critique of religious fanaticism, since there is nothing supernatural about it, which doesn't usually happen in films that have some contact with entities and religion. Others refer to the plot as a psychological horror, considering the protagonist's traumas, her mental conflicts and the perversity (intentional or not) of Tin and Tina. In addition, the movie is very suspenseful with some bloody and agonizing scenes that will make anyone bite their nails. In short, the movie ends in a very superficial way, leaving several explanations along the way that, like it or not, are missed by those who watch it.
