Holy freaking cow.
Gonna break this down:
First of all...I hope the VO is Roku. I really hope the VO is Roku.
The shot of the glaciers is beautiful. The waterbenders moving the boat? Really good detail. I love the motion of it, and also the repeated lantern motif for the Water Tribe.
The iceberg design is taken straight from the show, looks even better in a real life setting.
Aang is then doing some moves in front of an island, and the moves look somewhere in between air and waterbending, but he's not moving anything. I want to know where he is!
And then the shot that's so like the series that I had to back it up to see if that's what I really saw. So faithfully rendered, and it looks like it's all women and children out there, except for Sokka. Also, note the huts in the background. Cool.
Random Firebenders being evil, but I like it, especially with the rotating shot of Aang witnessing the destruction. He looks really young in that shot to me, and I think it really makes the scene poignant.
The firebending/earthbending scene was so, dare I say it, real. The way that the earthbender was completely physically entrenched in his effort to keep the wall up against the fire was very cool, and I like what they're doing with the bending here.
Then some shots of Aang doing some general butt whooping. Looks good, but like Atalla, I kinda hope that's the slow-mo version. Airbending's supposed to be light, agile, quick, and though this is dramatically cool, I'd like to see it stay true to form.
And then the Waterbending. At first, I was slightly disappointed that the water wasn't as neatly pulled together in one solid liquid form, but the way this looks makes it even more real to me. I like it.
The only thing I'm slightly disappointed with is the image of the Avatar State. And that's kinda nitpicky, really. The eyes look dumb. Other than that, good work again.
The set design and attention to detail seem really good, and the coloring keeps a pretty stylistic look that reminds me of the show.
I like the music for promotional purposes, but the music of the first was what I'm hoping to see in the whole movie. That was pretty well developed.
The first trailer was exciting, pretty and dramatic. But now I'm really excited.
