38 Iconic British TV Shows From the Past Decade That Everyone Should Watch

One of ITV's flagship dramas, Unforgotten tackles a new interwoven story of lies, deceit, and murder each season and brings some big names in British drama with it. Each series tackles a new case, with Nicola Walker's Cassie tasked with diving into the history of a community or group of friends who are somehow connected to a recently discovered dead body. Season 3, which involved the discovery of a teenage girl's body on the central reservation of a motorway, was a particularly memorable, and dark, tale. Season four is coming.
