I'll just say that the art is FANTASTIC!

I, for one, have been pretty happy with Costa's work. It hasn't necessarily been your typical Transformer story, but I like that fact about it (although why the UN Skywatch seems to be purely American based confuses me...)

And the first page should forever be held up as an example of how you keep characters consistent, without holding to a "house style". Nick Roche art doing Don robot designs. Awesome.
