I follow several loops where Castle is torn apart because of the "technical" things presented in the episodes. In my opinion, it doesn't matter. Why?
As a writer, I love the series for the characters and their interactions with each other. I adore the relationship between Richard and his daughter and mother. Richard is the perfect hero. He's witty and very amusing. The attraction between him and Decker is wonderfully portrayed. I wish I could mimic this in my novels. Both characters are superb at portraying their emotions through eye contact and body language. It's not the "murder" and the way it's solved that draws me...no, it's the characters and what makes them tick that pulls me to the television every Monday night.
So, what about you? Ever watch Castle? How do you feel?
