I remember the first time I watched The Exorcist (1973) when I was a kid, it scared the hell out of me. By now I rewatched that movie alot of times and it's still a classic in the horror/possession genre. To know what happened before is a good idea for a movie. The first prequel they made, Exorcist The Beginning (2004) wasn't great at all, rather mediocre, and so when I read this version was better I got a bit excited. But the truth is that this movie isn't much better. The first half of the movie is interesting to watch, but as soon as the horror part should begin you immediately spot the awful special effects and horrific CGI's. When you compare a movie from 1973, with decent special effects, with a movie from 2005, or 32 years of advanced technology, then you can only conclude that this isn't good at all. The prequel for one of the best demonic possession movies deserves something better than this.
