Not bad. A little drawn out. Good acting. First off, the acting is good (just ignore Glenn Beck). The lead prisoner is really good and I hope he does more work. The actor playing the doctor is ok. The writing is a tad long winded. Story is ok. Production is ok. Cinematography is ok. Ending is just meh. Because it has a political casting choice, it feels like the movie is propaganda for religion rather than just trying to be a scary movie. It would have been better to flush out more back story with lead up events to the prison. But overall, the movie is ok. Just needs more story, slightly better acting, less political casting, and some deeper story.
