If you were a fan of the TV show, Castle (I was), then chances are you're going to like the new show that premieres tonight on ABC. It stars Rachel Bilson as an actress who has been in rehab and comes out and starts shadowing a Private Investigator played by Eddie Cibrian. Not unlike how Nathan Fillion's Castle was an author who helped police detective Beckett, Bilson will help Cibrian solve crimes. Will you watch? I know I'll at least give it a shot. What about you?
