After the burning trashpile that was Gundam's ending today, watching this was refreshing. The show ended really perfectly, not too much drama, not too much comedy, perfect balance. The final statement ended up being very poetic and fitting the narrative very well. I don't even think it needs a sequel of any kind, the story is ideal as it is, leave the rest to interpretation.
Basically, really good shit, I'll remember this one for sure.
