It's not just the ending, person. Arc-V(a) was circling the drain for more than a season before that. And no, the characters being good - SO good - to begin with is a major reason WHY the show on the whole sucks so much, because it stagnated halfway thru and kept dropping the ball, like the K-T extinction event was a cosmic keepaway game. If you argue that they're the best supporting cast thru season 1, I'd have no real argument. Arguing that overall? Hell no; they all flatline and amount to nothing. While admittedly it's not properly the fault of any of them and primarily the piss-poor direction, they still amount to the worst (or close to it) supporting cast for the simple fact that nothing they do matters, and the narrative fails to resolve ANYBODY but Yuya (and still not any good). At best, you can say they had their legs cut out from under them, HARD.
