I'm a huge fan of Nathan Fillion. Loved him in Castle, and I love him in the role of John Nolan. When I first started watching this show, I wasn't entirely sure I liked it. Now, I love the show. Its subtle comedy, along with heart- pounding action and drama, is everything I ask for out of a show. I've also come to love the other characters and look forward to new episodes each week. Really hoping The Rookie gets renewed for a third season.
