A couple of observations:
-Again, the music they chose for the trailer continues to delight me. It may sound like "generic" rock, but synced with the action shots, as things get more dire for Cap and crew, the chords get heavier, like they're descending. And there's some great cues with the cars getting overturned. Basically, the entire section from when Cap gets on the elevator, to "Gear Up" to the Helicarrier exploding, it's an absolutely great musical and visual sequence.
-I'm more convinced than ever that RR's "helped shape the century… do it one more time," is
-Also, I, apparently, cannot stop watching the trailer. I've probably watched it 50 times today. Ugh! I need this movie to come out ASAP!
