Castle: The Complete Sixth Season

At last! Wedding bells may ring for Castle and Beckett, following five seasons in which bestselling mystery novelist turned special advisor to the NYPD Richard Castle (Nathan Fillion) circled around and flirted with Detective Kate Beckett (Stana Katic) before finally proposing. The couple spend time here planning their dream nuptials, but their partnership undergoes a real strain when Beckett takes a new position as an FBI special agent in Washington, DC, one that requires her to keep cases secret from Castle, although things quickly improve when she returns to her old New York job. Meanwhile, Castle's daughter, Alexis (Molly C. Quinn), drops out of college and moves in with her first serious boyfriend (bringing out the concerned parent in Castle), and Castle meets his father (who turns out to be a secret agent, played by James Brolin). One episode finds the squad pretending to be back in the '70s (complete with old TV cop show swagger and fashions) to help an addled witness recall a long-ago crime, and the finale delivers a wedding day cliffhanger. Breezy and self-aware, Castle delivers lively team camaraderie, a self-referential sense of humor, and crimes that all sport some kind of clever twist—just like a mass-market paperback mystery. Compiling all 23 episodes from the 2013–14 sixth season, extras include episode commentaries, behind-the-scenes featurettes, deleted scenes, and bloopers. Recommended. (S. Axmaker)
