El habitante is the best possession horror film I have seen in decades. I think I would score this one only second only to The Exorcist (1973). It does not have expensive computer generated graphics found in American films. But what it does have is a better screenplay than most possession films. I was enthralled by manipulative dialogs between the characters and the demon. How the demon digs deep into the characters past to weaken them morally and uses it against each of them to create hatred, doubt and chaos. Best of all, it has a main theme about forgiveness. This film without a doubt will go unappreciated by the masses conditioned to jump scares and expensive CGI. But for those who like to look deeper into a film's message, especially if you come from a Catholic background in a film like this, you will probably like the story.
I am giving it a 10 because I found the Catholic references authentic unlike the made up BS hollywood and the tv studios make up in the states. Can't tell you how much I cringe when the best dialog american possession films can come up with is having the priest yell "The Power of Christ compels you" for twenty minutes while beds float above the floor. At least this film has a real dialog between the demon and the protagonist in the film.
