While it has it’s inaccuracies, The Hurt Locker is a movie I’d heartily recommend. The most impressive parts of the film for me were those depicting the stressful situations the soldiers were in while doing their job, ie; everyday life for a U.S. combatant in Iraq circa 2004.
On a completely different note, I also liked The Fantastic Mr. Fox, a movie based on the book by Roald Dahl. It wasn’t a kiddie film by any means. As Ross Douthat put it in his review for National Review (NR subscription req’d).

In Dahl’s book, the foxes and badgers are delighted to live permanently underground, feeding off the farmer’s storehouses, while their enemies wait in vain for them to emerge. In the movie, things are more ambiguous. “I’m a wild animal,” Mr. Fox tells Mrs. Fox (Meryl Streep), explaining why he can’t stop taking risks, and there’s a sense throughout the film that this wildness is imperiled — that the farmers may be defeated, but that the animals will be forced to domesticate themselves in order to survive, living more as parasites on civilization than as the hunters they were meant to be.

And the animation style is compelling.
Finally, I haven’t seen Avatar yet. (If you haven’t guessed, I tend to be a little late in my movie viewing habits!) But I did finally see Pocahontas. Ehhhh….sorta-typical Disney pc fare–only mild de-programming of the children required, post-film. But if, as they say, the former is merely the latter with more flash and bang, perhaps I’ll pass.
