I had more problems with making horny teenager drama a focus of the early story than any sort of fan service. Also showing an emotionally abusive relationship as cute or funny is gross no matter how you cut it.

Further, I don't think I can ever beat the dead horse of unnecessary westernization too much. Virtually ALL the conflict in the series is about the world struggling to westernize. Politics, social structure, technology, the whole fuckin cultural spectrum and it's all psuedovictorian eurocentric TRASH. I loved all the subtle (and not so subtle) nods to all sorts of asiatic cultures and they threw it all away for cheap, overdone turn of the century cosplay.
