Katrina Bowden, the knockout receptionist of 30 Rock fame, has among the best pair of legs you will ever set eyes on.
That's the only good I can muster for this horror film as weak as Montgomery Burns. No scares, not even tingles. Even the 'boo' moments are bore moments. Some of the worst CGI you will find. And a cast of annoying, or dumb, or annoying AND dumb characters. No atmosphere nor intelligence went into set design either: a prison abandoned for 50 years still has shiny metal surfaces, no dust, and even working electricity.
There are a number of unintentional laughs though. So, there's that. And Bowden's short-shorts.
Good luck with the rest.
