Do you think that if Bojack wasn’t famous or any other characters in the Bojack universe for that matter, would the show still make sense? I mean if Bojack was a normal being with a normal boring everyday job with a mundane, repetitive life would he still face the same magnitude of consequences for his actions?
The pros and cons of fame, and the toll each takes on a person, is a central theme of the show. Celebrity culture, children raised by TV, unchecked excess, drug abuse without the traditional normal consequences because the rich and famous are held to wildly different standards; all of these are central to BoJack’s thesis as a piece of art.
Without all that, it’s just a (realistic, mind you) depiction of addiction. Which isn’t bad, and does still hold together, but it isn’t BoJack anymore.
