It was fun figuring out the science of the world as much as we wanted to figure out, and then playing fast and loose in other places. Which we do with our show in general. One of the things we love about the BoJack Horseman show is that we can always fall back on, "It's a ridiculous cartoon." And it is! It's a serious, relationship-based grounded character tragedy, but it is also a ridiculous cartoon.

In a certain way, sometimes it does feel like we say goodbye to a character, and we don't want to bring them back unless we have a good reason. We left the door open if we wanted to use him more. I always think it's better to leave the audience wanting more.

I don't know if that's the best story for BoJack, long-term. I do love the world, and I love playing around in it and it feels like an elastic enough world that, any story I want to tell, I can tell about these characters in this world. I can talk about parents and children, husbands and wives, the troops, or Hollywood. It does feel like an endless playground at this point, it would be a shame if we cut it off early for fear of repeating the same things over and over again. But I am looking to move the story and character somewhat.

We often ask, "Do we have enough humans?" Because it's always fun to come up with an animal in show, but it begins to feel like overkill.

I am wary of repeating myself too much. In this age of Netflix, as a Netflix show, if you want to go back and watch a season 1 episode, you can do that easily. I'm not interested in repeating the same story beats over and over and over again. But part of the truth of BoJack story is about how much he repeats himself and these patterns that are difficult to get out of. I'm trying not to be evasive about that. I'm not using that as an excuse. I think that's convenient to fall back on as a TV writer: "Oh, it's a show about stagnation."

One of the things I've found really interesting about the show is that a lot of people really relate to our animal characters, more than we thought they would. Part of that is, because they are animals, people project themselves onto them. If BoJack just looks like Will Arnett, people go, "Oh, I know who that guy is. That's a Will Arnett type." But because he's a horse, people can go, "Oh, I'm kind of like him in some ways."

That's part of the comedy, too, is we do have jokes throughout of hanging a lantern on the absurdity of the world. Like, when BoJack's flying over the neighborhood, you see some houses have swimming pools in the backyard, and what does that mean? Why would there be a swimming pool underwater? But we thought it was funny.
