This is one of those movies that almost can’t make up it’s mind as to what it’s trying to accomplish. Is it a teen movie? Is it a comedy? Is it a thriller? Megan Fox in her first starring roll, plays Jennifer. A young teen who gets mixed up with a band which dabbles in occultism. When a sacrifice goes bad, Jennifer is possessed with a Demon (specifically a Succubus) who lures men in on pretense of sex and then devours them instead.
This movie has one major merit, the make up crew did a fantastic job on making Megan Fox look truly demonic. One scene in particular is especially horrific, al la “The Exorcist,” that is really about it. The supporting characters carry Ms. Fox through the movie. This woman needs acting lessons. Period. If Megan hadn’t been in the movie, it might have rated higher in my books.
In a nutshell, if you like thrillers, this one is a renter, and nothing more.
