I think it's great that they are not making BoJack "just the douche" character. Backstories help a lot but it's also just about setting up the scene: can people be good in the environment? What are the motivations, challenges, triggers, and obstacles? Who defines happiness?
See, what you gotta do is take more time out, like this. Enjoy life. Like I do. - Maybe. Or maybe you enjoyed the moment a little too much. Had too much fun. That's why you are working for us now.
