Atonement's first 3rd is... brilliant. I never really got sucked back in... nevermind I'm not going to spoil. When it switches gears it drags in parts. Finally, I don't think the message the novel the movie was based is poorly translated cinematically. It's likely why the movie got nearly shut out at the Oscars, it was good it wasn't great.
You only win when you should. Just because No Country doesn't fit the mold of protagonist + antagonist - antagonist = protagonist does NOT make it any less of a movie. Javier Bardem and Josh Brolin have never been better. It's not saying exceedingly much for Brolin, Bardem is transcendent. He's truly an amazing actor, and if you enjoyed him in this you should see his other Oscar nominated role, Before Night Falls. Mar Ardento is really good too. I understand it's not for everyone, but the movie's so well done I am surprised there's so much negativity out there for it.
