The finale of the story didn't disappoint!
What did, though, was the art. Not that it was worse - but there was a lot of scenes of multiple machines fighting and often, the impression was "yes, very nicely done, but what am I even looking at?" Telling friend from foe, and who's doing what to whom, was often hard; and for all that I loved how not-human-like the machines tended to be, it did get in the way of easily reading the action.
With that being said, I still loved the final volume, and the story as a whole.
