No… it really isn’t.

First of all. BoJack had SEVERAL chances to move on and he only really started improving in the last season. While BoJack is far from redeemed at the end, he is still moving forward and he still has Todd, PB, and debatably Princess Carolyn in his life.

(Btw, don’t harass this person if you see them. All I’m saying is that I strongly disagree).
