Sam Mendes' follow up to American Beauty and Road to Perdition is a war movie focusing on a bunch of marines during the first Gulf War. It's structured somewhat like Full Metal Jacket, starting off with boot camp before shifting to the 'action' in the Middle East. And I put action in quotes because, for the most part, the film is about soldiers waiting around to see some real combat! All of their training goes to waste as they sit around running drills, going on patrol, and preparing indefinitely while missing out on the killing that they're all clamouring for. All the waiting eventually begins to take its toll on their mental well being.
The film doesn't really go out of its way to be anti war per se, but the absurdity of the situation and a few choice lines and scenes make its stance on the subject quite clear. It's a well crafted (as are all of Mendes' films) and darkly humourous film, and features a fine performance from Jake Gyllenhaal (though I still find it hard to like the guy in anything), but like Road to Perdition it didn't connect with me as much as I had expected. It's good, and worth seeing, but don't expect it to blow you away.
