She is survived by her two sons, Jonathan (and his wife Jeremy and their son Jon Henry) and Timothy (and his wife Karissa and their son Evan James), who released this statement: “The family of Kathryn Joosten, two-time Emmy winner, long-time Governor of The Academy of Television Arts and Sciences, lung cancer advocate, and so much more, regrets to announce that Kathryn succumbed to her 11-year battle with lung cancer today, June 2, 2012, surrounded by love and humor til the end. Thanks to everyone for their love and support. We are laughing through our tears. We love you, Kathy, thanks for everything.”
Bowen's performance throughout the course of the series has received mixed reviews. Entertainment Weekly 's Annie Barrett identified Julie as a TV character she irrationally hates. She criticized the character as being one-note and inconsequential and opined that Bowen "started off the series in an awkward phase and then we realized the awkward phase was going to last her entire life."  Following the announcement that Bowen would be rejoining the cast for the sixth season, Michael Slezak of Entertainment Weekly wrote that Bowen's performance is "so deeply unconvincing [that she risks] getting upstaged if there's so much as a house plant in a scene with [her]."  He also criticized the performances of other young actresses on the series and raised the question, "how come Desperate Housewives has such a dreadful track record with younger actresses?"  Following the character's attack in the sixth-season premiere, Entertainment Weekly 's Tanner Stransky wrote: "What I love about having Julie in peril in the first episode is that it's shocking and totally unexpected. She's a big enough character that I care about her and know a decent amount about her, but it's not like [a more important character] was knocked off the show."
