Castle is about a famous novelist named Richard Castle (Nathan Fillion) as he teams with NYPD detective Kate Beckett (Stana Katic) to solve mureders. As they investigate these murders they build a strong relationship both at work and in their private lives. Nathan Fillion and Stana Katic just have such great chemistry...at least on screen, off not so much. They apparently did not get along in real life and that was a big reason the show stopped after 8 great seasons. Those two are definitely the best thing about the show but not the only thing. The rest of the supporting cast all pull their own weight too. Each of them is what makes this show so special, there's not a weak link among them. This is a show where you can watch it more than once and still not be bored.
