Just saw Children of Men too, and, again, thought it was great. Best big budget, "just going to tell a story, thanks" type movie I've seen in a long time. I normally find Clive Owen a little in need of a cock punch, but he did well.
Please don't take this as an anti-American thing, but I also found it refreshing that a Hollywood feature felt so steadfastly British, even down to the soundtrack with Tavener's score, King Crimson, Deep Purple, Roots Manuva and some bits of dubstep.
Also cool, given it's set in 2027, that the aging hippy character was listening to music like Roots Manuva and some berzerk electronica, rather than anachronistically listening to (solely) 60s hippy stuff.
Yeah, fuck. It was a treat!
