For what it is, it's not a bad movie. The potential was there for more. I have seen other people say that thing is horrible and some say it's great. I think the mix on opinions is because some of the actors really were good, but one of the female actors, was not. The plot was interesting enough, but one of the annoying things for me was, they were wearing hazmat suits, and the amount of times they took their masks off. If they have to wear it, and work truly concerned they wouldn't be taking them off every other minute to talk. Once the movie gets really going it hits a good stride, But then loses a lot of steam at the end. I don't think it was explained well enough and the special effects on the bad thing were not great. The infighting between the characters was a little annoying between me, and the technical part about cleaning didn't seem real enough, but for a cheap little hard movie it's not bad. Keep my attention anyway. The ending was just a little rough for me.
