PZ Myers of Pharyngula points out the obvious: it is not pro or anti-war, it shows the fight between evolutionists and creationists!:
Look at the beginning. It's all about how the Spartans are the products of intense selection; the weak are culled from birth through adulthood, resulting in a collection of perfect physical specimens … exactly like all evolutionists. Unlike the real world, where our modesty compels us to conceal our awesome physiques beneath our lab coats, in the movie the Spartan products of evolution proudly expose their muscular pectorals, washboard abs, and snugly cupped packages. The Spartan women are also fierce and beautiful, like all evolutionist women. If everyone only accepted evolution, they too could look so ruggedly handsome (←note clever 'framing', in which I appeal to layperson's machismo and vanity).
*ahem* /fans face ... now I really have to go watch this movie....
