Forgive me if this has been done to death here, I’m relatively new to this sub. I personally always felt it was more poetically beautiful for Bojack to die. The tragic (anti)hero meeting his end after a chaotic life of destruction to himself and everyone around him. I don’t hate the ending we have, but I always felt there was a certain beauty and closure that felt right
Would counter the main theme: life doesn’t have a hard ending, it just keeps going. Life’s a bitch and you keep on living.
Him drowning would be as bad as an ending ax GOT gave us. A travesty. A disgrace.
