"If we had gotten canceled, and nowhere else picked us up, we probably would have written the rest of the series and just put it on my YouTube [page],” she continued, noting that they would have “changed the name slightly so we wouldn't get sued for rights."
“It's a finite story with a beginning, middle and end,” added executive producer Aline Brosh McKenna (pictured top right with Rachel Bloom). “We'd always thought of it that way. It's somewhat of a slender premise, and we felt like this was sort of a prism that we examine from four angles. It doesn't really replicate itself. It has to have a progression, we felt."
According to Bloom, each season of the series was viewed through a different lens of what it meant to be “a crazy ex” from the inside out. Season one was very much about Rebecca creating a romantic comedy because of her inner chaos. Following her diagnosis in season three, season four will focus on recovery. "The fourth phase is kind of recovery and starting from scratch," she explained. "In a really fun way, every season of our show kind of feels like a mini new show, so it always feels fresh and it always feels new."
"We deal with recovery and the redemption, but also it is a romantic comedy," added McKenna. "The back half of the season deals a lot with her romantic life once we've kind of landed and settled in on more of the issues in her emotional life."
Despite getting to close the Crazy Ex book on Bloom’s terms, the cast is melancholy about filming the final chapter. "It's bittersweet," shared Vella Lovel, who plays Heather. "We've all just developed such a community in support of each other, which has been so special and amazing."
"I think it's healthy in a way to be able to, when we wrap, say goodbye with closure," added Donna Lynne Champlin, who plays Paula. "I can't imagine how awful it must feel to wrap a season and not find out until four months later that you are not getting renewed. So it's actually really, really fantastic to go into this season knowing that it's the last one, just emotionally and socially, because we have sort of become a family.">
