I see 300 as an all-too-obvious propaganda film geared toward glorifying democracy, de-Humanizing and demonizing Middle Easterners in general, and drumming up volunteer military enlistment.
I see the 3 X-Men films as an allegory on how Homosexuals are treated in America.
I see Crash as a beautifully crafted comment on our racist nature.
I see Superman Returns as a re-telling of the Christ myth. So was Chronicles of Narnia to a degree.
I see Kingdom of Heaven as a vehicle to stir up more vitriolic hatred between Christians and Muslims.
I think The Green Mile had a decidedly liberal intent. As did Born On the Fourth of July and Babel.
And "E.T." was undoubtedly intended as an apologist glorification of the illegal immigration issue... We just didn't know it 'til now.
