@ayase Thanks! I so personally agree with you about dissenting voices and opinions always being welcome in threads and fodder for discussion. I'll try to remember there are others who also feel the same about this, and chime in whenever I can!
The current political cultural landscape certainly influenced the way I expressed my feelings in that review, and to an extent perhaps my interpretation of the show's stance on environmental issues. But I don't think my core feelings about GL would have been too different had I watched the whole series in 2010 or whenever. My comparing it to Donald Trump was probably a little unfair and wasn't really very deep or well thought out. But as Trump and talk of him has been all over the media during my watch through of GL, I couldn't help but be struck by what I felt was a certain affinity between the two. I also don't dislike Trump or GL for being brash or bold or loud. But I suppose it comes down to fact that I just didn't believe in the Gurren Lagann that believes in anything very much.
Ok maybe not nothing, it does have a message of self belief, brotherhood in arms, perseverance and even a quick bit of forgiveness. None of that is bad of course but just the stock principles every shonen story must have, and even then, for me personally, those ideals felt less weighty in GL than in other similar stories. I think it's partly because I felt that the characters lacked weight and depth and personality. But also the show generally seemed to have a pretty dim view of humanity outside of its capacity for fighting and expanding. It doesn't seem to believe in politics, law, democracy or community, nor religion either (not that I begrudge it that last one). But I noticed very little kindness or warmth at all (in this regard the two kids in Yoko's class stand out as an notable exception, but even here Yoko seems intent to stamp it out). It had heaps of macho posturing though.
Team Gurren fought long and hard to be able to live on the surface at last, but to what end? The society they established seemed barely better (and maybe worse) than what they had underground, unless we're expected to simply equate big city with better quality of life? So it felt like the fight isn't a means to an end, but rather the end itself. And quite literally as the show triumphantly closes with the spiral nemesis barely considered but still looming large. For me, the show's action itself just wasn't good enough to justify this perspective.
I do absolutely understand that many will heartily disagree with me about all of this though! I can definitely see how other people interpret the show completely differently from me in all kinds of ways. There isn't one fixed meaning to something like this. I'm pretty comfortable to read political allegory into a work even when I'm unsure of the author's intent, and maybe even when I doubt the author had the intent. I think a work of art leads its own life and becomes its own thing, and becomes all kinds of wildly different things to different people.
