I generally agree with the criticism here, though maybe not as harshly. It felt like they had a bunch of cool ideas for the setting, but never had enough time to flesh anything out in detail. So by the time the finale came around, a lot of stuff either didn't make much sense, or came off pretty badly (beastmen being unable to coexist peacefully because of an inherent genetic condition is questionable, to say the least.) I think Awoo's take on it being a critique of liberals is fairly accurate regarding the protagonist, but the rest of the characters kind of just struck me as standard archetypes without much depth. I don't think the issue was a lack of episodes, it was more that Trigger didn't really plan anything too deeply outside the two main characters. That all said, I think it still showed a lot of promise and could be a really interesting series if they took things further, provided they give more careful consideration to the themes, characters and overall plot.
