Do you have a number of seasons in mind?
Rachel Bloom: I think the ideal number is around four. That could change. We’re a show about a very specific journey in a person’s life. And it’s not really a sitcom meant to spit out copies of itself. Very early on, we called it a 50-hour movie. I think we’re beyond that now. There’s always going to be plot movement, so there’s only so far I think you can go with that. It could be five, but I think around four would be ideal for us creatively.
