Something to add to my Dallos post that didn't fit the flow: It is a very "me" thing to appreciate, but I liked how "80's" the whole thing was on nearly every level. Certainly the fashion, which was great, even including the hair - vibe me bros:
But that isn't nearly as important as the plot stuff. The story is steeped in, essentially, collectivism - concepts of nationalism, "society", generational movements, and so on. It feels like something made by, well, Japanese people who are part of a society that still strongly remembers World War Two, who still feel the "axles of history" turning under their feet. A modern show like this would have characters who are far more internal - a teen girl who loves hanging with her friend circle, "thrust into the war" by unfolding events. Here though, while what societal force one belongs to is up for debate, that you are a piece of a wider puzzle is a given.
And, of course, all of this is set in space, in the peak aesthetic of the mid-century sci-fi boom. The technology of this era is actually very load-bearing here - the people on the moon are manual laborers doing mining. They don't use drones, they pilot these suits individually, no internet exists despite them having moon colonies. No internet is important, because they can barely talk to Earth! If they had internet, kids on the Moon would watch ASMR reels of Caribbean beaches and kids on Earth would follow MoonTubers. Today, anime has humans piloting the mechas because that is the genre, right? We know it is stupid, these would be largely AI-piloted in practice. But here the technology has a level of realism to it that you can only get by authentically believing in a different future.
A lot of this plot/theme stuff is being pulled, not from the political theorizing of these anime creators, but from the stories they are inspired by. The Moon Is A Harsh Mistress is an obvious source here, and that story is deeply interested in libertarianism and future tech because of course it is. And that stuff trickled down to anime OVAs, however obliquely. Much different stuff trickles down now - hell if you wanna be a hipster about it, you can debate if anime largely trickles into itself and draws less and less from outside sources these days. With Dallos, in 1983, the cultural basket is just so different, despite it being a pop action show - you not-ironically could not make this show today.
