Low budget horror that follows the crew of a TV ghost-hunting show as they investigate a haunted prison. Not 'found-footage', thankfully. No 'name actors', other than Dee Wallace, who gets an early scene as a foul-mouthed, ball-busting network exec. The location (the real life, closed Missouri State Penitentiary) is terrific, the cast are far better than normal for this sort of thing, and whilst the story is pretty generic, they do go for a 'twist'. Unfortunately, the CGI looks cheap, the music jars sometimes, and - despite the great setting - there isn't much tension. 5/10.
