I didn't hit me as hard emotionally as I was expecting it too. I liked the characters and cared about their plights quite a bit, but it didn't quite grab the way reviews have made me think it would. Not to say I was cold to it, just not bawling like a baby.
That said, since I've slept on it, I can already feel it gnawing on me. What a dense, rich movie. So much to chew on, such sincerity. I very much want to see it again. It's so densely packed with echoes, ripples, call and responses. The theme I think can be stated simply, but the way it's told is anything but. Very daring filmmaking.
It's like the anti-Prometheus.
