This movie is actually pretty good,. The characters are likeable, except for the woman cop who is awful, the idea is creative and the deaths are gruesome. The blood and gore effects are believable. I thought the whole movie was quite entertaining. It won't appeal to everyone but I would recommend it to anyone that is looking for some gory fun without it being"too much" you do have to pay attention to some of the explanations or you might not understand it. That woman cop dies in a great fashion, let's just say elevator 1 bad woman cop 0! So I would say give it try you might actually be surprised!
