I've seen it twice now, and plan on seeing it tomorrow and saturday as well. I thought it was great. A lot of these reviewers simply do not understand the mythos, which is why they didn't like the ending, as was bloody disgustings oppinion. When Mrs. Yutani says "the world isn't ready for this technology", and corporal Stevens says "Yes, but this isn't for this world, is it?", any true fan knows the line is referring to the motto of the future merged corporation, WEYLAND YUTANI: BUILDING BETTER WORLDS.. it's a no brainer. As for the reviews finding it arbitrary that a predator would care if humans knew who they were, umm.. well, they DO. It's a matter of honor and security which forces wolf to head to earth. Having an entire eco system wiped out by their missteps is considered a shameful display to the youtja, AND, any technology left behind could be used against them. I'm just saying.. don't let these reviews get to you. TRUE FANS will appreciate this film.... TRUE FANS.
