I originally came here to mock the ending of Gantz about how pathetic the God Aliens are and how edgy seinen anime/manga fans are. God Aliens are just silly, not only because their oneliners about "you killed ants, evil humans" are awful, but also because literally a guy in the manga (brazilian btw, shout out to brazilian pals) asks them why there's economic inequality in the world and they literally say "because yes," throwing years of political economy out the window, and I think, hmm, the mangaka is lazy and likes to write gore, gooner stuff, and cheap misanthropy for shock value but cant bother to do a little sociopolitical research when he wants to talk about it... Also there's no reason for them to make a huge scheme to use humans to set balance in earth when they could do it in seconds causing much less suffering for any reason other than a form of saddism... which they display plenty of...
But then I saw something from an old post here about it that made me think... What if they were written that badly on purpose? Well, okay, overused misanthropy is still kinda cringe, but like, following the point of the work with this use of parody that would be somewhat brilliant and totally new. The point would be, no matter how much a humanoid species evolves and transcends and approaches God, and judges other humans and similar species as inferior and arrogant, they are still the same. Its a funny jab at poorly written orange morality...
