Square is doing an excellent job of keeping the plot from the public. This is a good thing. Even though I don\'t want to know what happens before I see the movie, inevitably, just cause I want to see it soooo bad, I\'ll look it up on the internet if I can. From watching all the trailers in a row, I\'ve come up with:
A) The army isn\'t evil, but they might be on the wrong side, or do "evil" things to get what they want.
There are multiple aliens, probably at least some are benevolent (the one in the doctor?)
C) There are... uh... less benevolent aliens, including some very powerfull ones, which seem to enjoy dismembering us puny humans. Probably the "boss" evil guy will be some alien they wake up...
