As a die-hard horror fan, a fan of Demonic Possession films, and a fan of great acting, I immediately wrote off this movie as being another Hollywood cash grab. Blumhouse is the worst thing to happen to horror since Rob Zombie started making movies, so seeing as this is another bullet to add to their arsenal in murdering the horror genre, I was weary about watching it. Couple that with the film not having any marketing up until a few weeks before it was released, and all of the signs pointed to a very half-a$$ed film to join the ranks of all of the other failed horror films of the last 10 years. After watching it, however, I am very glad to have been proved wrong. Incarnate ended up being original, entertaining, and the acting was really top notch, especially that of the three leads.
The problem I have with Possession films is that they rarely deviate from the formula; girl is possessed. Family calls priest. Priest needs okay from Vatican. Priest battles demon. One of more people die. The end. That has been the premise of every possession film of the last few years. Surprisingly, this movie goes completely left field, not adhering to any of the clichés that make the genre so deathly stagnant. The demon is now a "spirit parasite", the girl is replaced by a boy, there is no Catholic priest in sight, and the people who die actually deserve it this time. The movie does so many things right that it is really easy to overlook the things is gets wrong, and everything from the special effects to the script is written with an actual appreciation of what makes these movies entertaining in the first place. Sure, some parts are cheesy and straight out of the horror handbook, but when they are handled this well, does anyone really care? It's much better than the abominations we have gotten in the past, like The Last Exorcism or The Vatican Tapes.
Overall, if you like Possession films, good acting, and movies that are not made for children and teenagers, give this film a shot. You just might like what you see. I was thoroughly impressed by this, and although Blumhouse has a long way to redeeming itself, this is a great first step. A solid effort all around.
