This movie sucks. It's a situation I've seen several dozen times before (and not done as well here), the characters are all underdeveloped and the makeup effects are particularly bad. I think the filmmakers were going for a DEMON's-like monster but did not succeed. The movie also takes place in a deep underground lab that has all these pipes and vents all over. Well, I want to know what all that plumbing is for!
Avoid this as you'll forget about it anyway five minutes after you're done scanning through it.
