Very, very moody and melancholy and slow and drawn out. Really really beautiful photography (cinematography?), particularly during the narration. Lots of Midwestern winter shots, snow covered wheat fields, sun dappled groups of trees. Empty rooms with wooden floors and empty rocking chairs and streaks of sun shooting across them.
Oh and yeah the acting? Brad Pitt is progressively manic (eventually becoming an actually intelligible version of someone similar to the character from Snatch) and Casey Affleck really grows on you, after seeming sort of idiot-savant like at the beginning. Mary Louise Parker was excellent in a (very!) small role, as was Zoey Deschanel. Wished Frank (Sam Shepherd) had made another appearance at the end.
At the end you realize the story isn’t necessarily about what it seemed. Thought the narration would be annoying, but came to love it (gives it a very storybook feel, kind of like the narration in Pushing Daisies, although in a very different genre of storybook).
And as I said, the photography was beeeeaaauuuuuuuuutiful.
