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.
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.
It takes a couple episodes to get going but once it does it transcends the medium and becomes something altogether different and fantastic. No show, animated or otherwise, should be able to elicit this much emotion from so much absurdity.
This is funny, dark, cynical to a fault, and the characters sometimes are beyond salvation until another well thought out moment of introspection comes, perfectly bumming you out while addressing the contradictions of today's existence. Currently, this is one of the best shows you can find on the mainstream.
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.
