4 TVs Hottest New Crime Fighting Duodeanlowdon | 07/09/2011 | See all deanlowdon's reviews (468)Top 100 Reviewer Top 100 DVD Reviewer Having killed off his popular mystery character Derek Storm, Richard Castle is suffering writers block and finds himself unable to even start his next book.When the NYPD asks for his help catching a serial killer taking inspiration from his books he meets Detective Kate Beckett. Strong, sexy and independent she is everything he has been looking for, and not just for his book...At its heart Castle is a police procedural that finds the duo tasked with solving a new crime each week. The twisting mystery of each episode is usually fairly entertaining and the ongoing mystery of the story behind the death of Becketts mother certainly adds a layer of emotional depth to a number of episodes. It is however the central relationship between Castle and Beckett that lifts the show above the bog standard cop show. Nathan Fillion is as good as ever and his on-screen chemistry with Stana Katic is simply electrifying.While it may be a little farfetched at times this is a show that never takes itself too seriously, rarely fails to entertain and continues to improve with every season.
