SERIES FINALE: After four seasons, this series is calling it quits – with style, followed by a party. Rachel Bloom, who stars as Rebecca, co-wrote this finale with series creator Aline Brosh McKenna, and provides a conclusion to the Bachelorette-type boyfriend competition begun in the penultimate episode. And Donna Lynne Champlin as Paula is there for moral support at the end, as she was in the original series pilot.
