Let me be clear about something. There isn't a war movie in this world that doesn't "glorify" war. But you know what? This is a work of fiction, it is a movie, it is escapism. If I wanted realism I'd watch a documentary. Whilst accurate, it does have some wonderful Hollywood flair (take the opening scene, just beautifully shot - my mouth was certainly agape watching that on a 42 inch on BluRay!!!). I've read some bad reviews moaning about how it makes war look 'awesome', and... well, get over it. It's a movie. That's like saying Left 4 Dead is bad because it glorifies the zombie apocalypse.
Jeremy Renner is just excellent in this movie, as is the remainder of the cast. Strong roles, amazing acting, and a gripping story and well written script to boot. This is an instant classic for fans of war movies, a good story, or even just good cinematics.
