If there's one word I would use to describe the whole show, it would be "superficial". The show brings up a lot of topics, some of them quite heavy and hard hitting, but never actually bothers exploring or diving into those topics any meaningfully beyond "gee the oppression of masses due to hypercapitalism sure is bad huh", "human experiments sure are bad huh", "war is bad huh". We don't see any ramifications or any depth to the conversations the show desperately wants to bring up to seem more mature, it's all just background fluff as far as the show is concerned. This theme of superficiality permeates through the characters as well. Mio and Suletta's romance never really goes anywhere nor is it developed any meaningfully. Mio just seems to be into Suletta back in the first season and Suletta very slowly reciprocates but even then Suletta seems to be doing it out of duty more so than genuine romance. Even with the faux breakup in the middle of season 2, their eventual reunion is nowhere as cathartic as the OP or ED make it seem. It's as if they've never broken up in the first place.
And, there is the finale, where all the plot elements teased in S1 and S2 come together , corporate politics going crazy with betrayals and uneasy alliances here and there, alongside with an out-of-nowhere superweapon threatening our heroes in one desperate finale. How could they ever resolve any of this satisfactorily in just one episode? The real yet depressing answer to this is that they didn't. Everything just ends up hunky dory in the end, everyone's happy, you're a millionaire and everyone's a winner! Hurray you did it! Suletta? Mio? Even the jailbirds are free outside of Saddick. And everyone's a forc- permet ghost so no one's ever really gone. Like, I don't hate happy endings, but you gotta earn it. And none of our heroes, Mio, Suletta, or even Guel, really earned this ending for themselves.
G-Witch is as shallow as they come, and it's especially disappointing considering the pedigree of Okouchi, known for his mad twists and crazy moments, or for Gundam itself which is fairly cynical and dark to begin with. And above all else, you can cram in as much symbolism as you want, as much robot fights as you want, but ultimately if you are gonna cop out with an easy exit to all the problems and dilemmas you've raised for your characters, you just don't got a good show on your hands.
4/10
