In my opinion Nathan Fillion is one of the most underrated actors in Hollywood. He has enough charisma to carry any show, even a theatrical movie, he has a very wide range in his acting and he always delivers with precision. Castle is a very enjoyable show, mainly due to the chemistry between the leads, but also because of Fillions lightheartedness and great sense of humor. For me the stories are a little to alike, we have a homicide, we continue interviewing suspects, but conclude every time that they could not have done it. Then we find the final clue and frame - the gardener. What I really, really love, are the Firefly references in the show, they always make me smile - when Castle shows up in a brown coat for Halloween or explains that he learned his Chinese skills in a TV show he really likes.
