While the subject has been explored in other movies, the Rite of Exorcism is, by itself, a very complex theme to reproduce. Some might call this movie a cliché or a waste of time, but it goes through another route altogether. It's not the "goes to the house exorcise demons" routine. If it could have been better handled? Yes, it could. There's some loose ends to the story. However, I did find it refreshing. Above all, never watch a movie with high expectations. No matter the subject, take it for what it is: Entertainment.
