This was pure, 100% brilliance. The battle scene was epic, the damage was well done and realistic, and the music fit the atmosphere.
The only quarrel I have is that the shooting during the actual fight scene lost the sense of scale; you got the idea that they were big, but some more steep-angle shots would have conveyed that better.
Past that, best. Movie. Evar.
I've been waiting for this to come out for some time, and hadn't realized it was released on robot day. Would make sense, eh?
