I strongly recommend you to. I think that, as war film, it could be even better than Saving Private Ryan, althought might not have the same pop impact.
Compared to Avatar, I enjoyed Avatar, but this isn´t worth an Oscar beside something like the Hurt Locker. This film is on this kind of war films wich are to the standard war films like what the "psicological terror" was to the terror movies. I mean, films like Saving Private Ryan, Waltz with Bashir, as opposed to Pearl Harbor, Black Hawk Down or the last Rambo film. I come to enjoy more the anti-war films than the "all-glorious" ones, those which don´t seem to have an ending, nor a morale.
About Inglorious Basterds, it something totally different. Not worth so much attention indeed.
