Spielberg's subtext to his version of War of the Worlds:
Aliens: A Too-Powerful America
Victims: The oppressed "peoples of the world"
Don't make any mistakes, Spielberg has cast America as the enemy in this movie. That's why he's telling everyone that his enemy didn't come from Mars and that they were always here.
It's leftist propaganda that should be boycotted.
No one who sees the film will walk away with an anti-American view that they didn't walk in with. The film is tremendous. Boycot it if you like, if you don't want Spielberg to get your bucks, but there's no reason to do so on the basis of content.
Well, once a leftist, always a leftist. I was impressed with "Saving Private Ryan", even though its plot reminded me of a bunch of kids playing "war".
