This is an exceptionally made movie. I got to see it theaters too, which only made it better. The film might be a tad slow in the beginning, but it picks up quickly once Reagan gets possessed and starts doing weird things. During the scenes where Reagan is flipping out, the special effects are incredible, especially for the time. They'll have things flying across the room, the entire bed shaking furiously, and of course, the projectile vomit. All of those look extremely realistic and they add to the super creepy atmosphere this film has. The voice they gave the possessed Reagan is perfect. If I had to choose a voice for the devil, it would have been that one. It really gets to you and makes every scene that has it way more frightening. The movie does have issues though. In the very beginning, they have this backstory about this little sculpture of the devil being found and I found it to be both unnecessary and kind of confusing. It isn't really clear if the devil got released because of that statue or what. I couldn't find a correlation between that statue and Regan either. Only other problem I have is the devil being very picky about how he uses his power. I don't understand why he just didn't break the straps and leave. I know they tried to explain it, but it doesn't really make any sense. Damien Karrass asked him that and he responded with "that would be a display of too much power" or something like that. He says that, yet he'll throw stuff all over the place and throw up on people, and even kill people. How is breaking some straps too much power? I call bs on that explanation. Other than those 2 problems, fantastic horror movie.
