What's with the recent resurgence of the "All Will Be One" versus Individuality theme in anime? This is like the 5th series in the past year, and the second this season. Not that I don't enjoy the allusion of a fight against socialism, Nanny-states, and possibly even as an affront to Buddhism...
At least this time Grace is trying to become the ultimate Queen Bitch of the Universe and it's not some delusional "everyone's equal" non-corporeal utopia.
I definitely echo the hate-Ranka-more now sentiment. For me, a lot of that came from the Sharon Apple projection she put up in space. This whole thing screams references to that last fight in Macross Plus, only it's Vajra instead of humans.
I was not pleased to see Sheryl's short monologue before she descended to the stage. She knows she will die, perhaps as a result of singing in this very battle, and she's just giving up. She doesn't even want to fight against Ranka, she's just pushing Alto into her arms by telling him to save her. I don't mind endings where the hero inevitably must kill the one he loves to save the world/universe/city. I miss those series from the late 90s, they had impact, like Gurren-Lagaan did.
I also agree with David here. Grace is way more powerful than we could have possibly suspected. She's spent the last decade learning exactly how to accomplish what she's attempted to do now. She's practiced plenty messing inside Brera's head too, now she's made him into a total slave. I had thought she was just wiping his memories again, but it looks like that is not the case.
