This show has serious theraputic value. Disregard the animation quality (good), disregard the voice acting (great), disregard how well it's written (amazingly).
This show pulls zero punches but is still mercilessly positive. It has helped me, and I know it has helped others. If that isn't a justification for a continuation, then I do not know what is.
I'd beg for just 2 more seasons.
