I highly recommend this movie to any Paranormal Activity fans. Although it is not shot in self-documentary style like Paranormal Activity, you will notice the similarity. And don't get me wrong, this movie is not the same story as Paranormal Activity by any means. The ending in The Ceremony, in my opinion, is actually much better than Paranormal Activity, but the different storyline allows it.
Don't let the title fool you. This is not a gory Satan worship movie. It is eerie and suspenseful, and does have the occasional, loud startling event to keep you on edge. But, based on my memory, I don't think there is a single drop of blood in this movie.
I have seen a number of movies in this genre and this one feels fresh. There are no annoying girls running around screaming and tripping over tree branches. The actions (and inactions) of the main character aggravated me at times, but that's the way it goes with most movies. He actually does a pretty good job making the film work. The main character plays a recent college grad who is halfway moved out of the house he and his roommate lived in during college. This half empty house provides a great setting for The Ceremony.
