A lot of it seems like standard middle-aged navel-gazing, heavily influenced by either Albert Brooks or Woody Allen, but made palatable for millennials by being modelled aesthetically on a children's cartoon series. However, the creative risks the show takes are actually quite ground-breaking, given the context; from wordless surrealist episodes, or episode-long monologues, to its clever use of narrative continuity.
Secretariat: BoJack, when you get sad, you run straight ahead and you keep running forward, no matter what. There are people in your life who are gonna try to hold you back, slow you down, but you don't let them. Don't you stop running and don't you ever look behind you. There's nothing for you behind you. All that exists is what's ahead.
Sometimes tries too hard to land jokes but ultimately 'Bojack' is a true gem. It's fucked up that the Sad Horsey Cartoon whoops its contemporaries in taking on depression, failure, asexuality, abortion, and irreconcilable relationships.
Two seasons in and so far it's quite disappointing. The jokes are more miss than hit, and the emotional moments would hit harder if the characters were more relatable; the beginning of the show, the crucial part for character development, does a shoddy work at making you care for them. The script has a lot of gems and a few episodes are amazing, but overall... meh.
