Just finished the TV series (the OVA and the ZOE 2 game are next), and it's probably one of my favorite mecha anime series to date. Dolores has a fantastic personality, never mind her great appearance, and how she meshes with James over time is heartwarming. I kinda wish more anime would have anti-heroic, anti-angst characters of this sort.
The ending was a little farfetched, and Dolores' new "form" doesn't seem right--she should've been rebuilt instead. Then again, it's still far better than other series conclusions I've seen *cough*Reideen (2007)*cough*.
