Tricksey!
Great review comments up thread. I also loved those moments. I was dazzled and amazed with this film too. I feel pretty inarticulate about it so far, needing to both see it again, and get some normal sleep.
The BEACONS! - The beacons were really neat. Really dramatic having all those lonely beacon guards called to action.... when they could not know what action, only the beacon.
I loved that part too. Very powerful.
