I did enjoy it a lot too and I am pretty much like in your case. It’s well written, the characters are all great but the main character started as miserable and ended up as even more miserable despite his many attempts at trying to fix things. I didn’t expect happy story but every time bojack tries something to fix his life it ends up horribly horribly wrong. It was getting so bad that I jokingly thought that if they continued like this there will be a scene where bojack will be helping an old women cross the street, she randomly get hit by car and the writers will frame it as to blame bojack for the accident.
