For the MPAA rating, I am not sure if it is rated PG-13 or R, but either way I think if could pass for both, meaning it looks like either a strong PG-13 or a soft R. Anyway, I found out about this movie months ago and have been excited to see it since, especially two particular scene where the son wakes up with writing written into his body and the when the shower curtain wraps around the chick. As far as generic, I do agree that yes it has a plot that has been done before, but like somebody already mentioned, people do have different experiences with the supernatural, if you believe in it or not. That being said, the trailer made the film look awesome so all I can hope is that it won't turn into The Unborn where the best scenes were already shown in the trailer.
