No real spoilers, just a very brief reaction because I have to collapse from sheer exhaustion now:
I think I'm going to cry now. Multiple times.
"Don't go where I can't follow you, Mr. Frodo!"
I think I teared up regularly about every ten minutes or so.
I think I may have to rethink seeing it multiple times in theaters. It is breathtakingly awesome, but too emotionally intense. I feel like I've been through a wringer about ten times.
