I just love this show, it's like the perfect mix of everything that makes other shows special. It has Rick Castle, who is a bit like the "light version" of Californication's Hank Moody, Det.Beckett a funnier, yet much more complicated version of the Mentalist's Teresa Lisbon, and the both of them are, of course, solving crimes together. It's a very eintertaining show, with many surprises.
Fans of Nathan Fillion will enjoy his usual humor and references. The actual stories and cases are quite interesting. People who aren't fans of theses types of shows can enjoy the show for much more than the murder cases.
