I'd watch if they did the aforementioned Castle & Alexis show, with Espo and Ryan chafing under some new (hilarious) Captain perhaps, and Hailey and that hot computer tech chick Tory at the station helping out, Perlmutter as the permanent coroner because he's always been funnier than Lanie, and Castle drowning his sorrow in hot 20-somethings. Beckett really serves no purpose on the show as it is right now anyway other than giving Castle a reason to be retarded. I'd be fine with watching her go. The housewives that ship the show, however, might not agree.
