The movie is best described as any typical poorly produced horror type movie where the characters will do the stupidest things to get themselves killed for no reason (eg.-walking into places knowing that you'll be killed or not taking anyones obvious warnings). The acting itself was not bad but the movie doesn't make much sense as to how a giant snake can move around the prison but can't really be seen until at least the last 45 minutes of the film. Some scenes were just written poorly. for example, dean cain promises a prisoner her safety when she was freaking out about the snake eating her and 5 minutes later, all he did was shoot her (but not the snake) so she wouldn't have to deal with the pain of being eaten... I guess that's still keeping his word. I'm no animal expert but this snake goes around this prison eating a bunch of people...don't snakes eat and then go hide and sleep it off since they're most vulnerable when they are full?? I don't think it's even worth the time watching this film. if dean cain would show some skin, perhaps it's still worth the rental.
