sorry guys, I hate to be a dick, but...
this cartoon embodies everything I hate about anime.
lure us in with the promise of fighting robots, and then have humans complaining to each other for the whole time. I was far to bored to care about any of these characters, and there was a lot of them to bore me. You did so much work with voice acting and lip syncing that you would think something good would come of it, but it was all that voice acting that causes this cartoon to fail.
I really liked the history line you laid out in the opening, it is an interesting world that could be developed. My advice would be to concentrate on your fighting robot animation skills, and then cut 80 % of the human characters.
just my opinion.
