"A whole new chapter in crime solving."
After a serial killer imitates the plots of his novels, successful mystery novelist Richard "Rick" Castle receives permission from the Mayor of New York City to tag along with an NYPD homicide investigation team for research purposes.
What viewers say
Viewers love the charm of the mystery novelist who tags along with a New York detective, and the playful partnership between the two is widely seen as the show's strongest asset. The tone is light, funny and far less graphic than most crime procedurals. Criticisms are that individual cases can be formulaic and predictable, and fans say energy and chemistry faded in the later seasons, with the final run feeling rushed. Parents note murder scenes with brief shots of corpses, constant flirting and some sexual references.
Best for: Viewers who want a witty, lighthearted crime procedural with banter and romance and don't mind formulaic cases.
