The more I think of it, the more I dont like it. They were too heavy handed with the big evil corporation bit and were always too eager to show gross stuff.
Spoiler:
When the Alien first completed the liquid and put it in the cylinder, why didn't they just jump down the trap door and go to the mother ship then? "No, lets wait and talk to these angry humans first!" The intelligence and behavioral difference between Chris and the other aliens was too great. The Colonial was also a lame b-movie type villain. He yells at people, is cruel, enjoys killing, too tough to take orders, and he shaves his beard stubble?
Seeing this movie makes me feel better about not seeing King Kong.
