I loved this show.
Most of the main characters were really likeable for me, and if some were not, they were relatable. Some of the corpo-related story elements flew over my head, but i understood the overall plot, and found it engaging enough.
The fight scenes were not that fun for me. I mean they were well animated, but the choreography was hard to follow most of the times (especially later on, when it was not just 1v1 mech battles). But overall i knew what was on stake, and i eagerly waited for the conclusion of the battles.
But like i said, the characters really grew on me (not just the main duo), and now that its over, i actually miss them.
