The cast in the movie survived things that nobody could survive. The electric fence by the girl. The shot to the liver by the man who picked up the organs for transport, and afterwards he seemed to get better and better. The girl also did well against the tear gas, while everyone else surely needed masks. So basically quite unrealistic. And she made some very bold and yet stupid moves. One of which was by checking on the ex-boyfriend when she clearly could have gotten caught, due to the long amount of time she was exposed. They had some tense moments, and it wasn't bad for a movie shot mostly in one location. The coroner, played by Jerry O'Connell has been around a long time and he is often the Good guy, so it was nice to see him as the villain.But overall, a rather only okay horror movie at best. I can't get over the girl just looking so dumb in the movie. But I am not at all talking about the actress, Bailee Madison who played her. Maybe it was just something I thought about her, I don't know.
