Jeez, as a legit attempt of anime in the US on a major network, this show is the worst! Majorly flat useless characters and the techno jargon is actually offensive to anyone that codes. The socialist Chinese utopia against the repulsive capitalist North America metaphors would be offensive to both sides if it the dialog wasn’t so pathetically stupid. I feel stupider for watching.
