Well, I went and saw Return Of The King a second time with my brother-in-law. We both agreed that it was even better the second time around.
We noticed more details this time, because it wasn't so mind-blowing. The main battle scene at Minas Tirith seemed to last a lot longer, because it wasn't such a whirlwind. It was absolutely awesome!
I hope it sticks around through this next weekend - I want to see it one more time on the big screen.
