Yawn. Another Hollywood programme-your-mind flick to force you to believe any non terrestrial life is going to steal your babies and eat your liver with a nice Chianti and fava beans. It will work for the corn syrup brainwashed masses of course because they fail to question the logic of why didn't the technologically advanced aliens do it a thousand years ago.
The universe is a big place.
Naturally they also have those project Bluebeam/SKUNKWORKS visual effects to hoodwink the people into thinking good is bad and bad is good but we're just going to have let the chips fall where may, and make some judgements knowing that the Pentagon and Hollywood have demonised Nazis, Commies and Muslims in that order to get their way and that word has already leaked that the next round is an alien invasion - Do they know something we don't?
Anyway, should that happen, expect me to side with the wicked aliens just in case the chance to take some chunks out of the military industrial complex avails itself.
