Why was Val Kilmer in this one? It makes no sense to me. I know he's growing old and his last castings were not the best, but still.
The film is a classic isolated monster/contagion movie, featuring most clichés you would expect. Brave and good looking chick, check; black and Asian representation, check; cowardly hysterical jerk, check; scary but completely implausible premise, check; mad scientist, check; brave guy that saves the girl, check. Actually, the formulaic concepts were so absurdly respected that when there was a scene where they would cut some guy's arm off to stop the contagion, they didn't actually show the cut. Same goes for when the girl had to strip to check for contagion. No problem showing flesh crawling bugs, though.
I could debate the reasons why the film made no sense to no end, but I will tell you just this: prehistoric bugs that come out of the thawing ice will NOT make me think harder about global warming. This theme is largely responsible for why the movie sucked so much.
Bottom line: couldn't even give it an average 7. The effects and the atmosphere (if you ignore the actors completely) are the only two good things happening here.
