Netflix's "Legends," set in the 1980s, follows undercover customs officers, led by Steve Coogan's Don Clarke, tasked with combating the rise of heroin in Britain. The series, reminiscent of "The Gold," uses a historical backdrop of Thatcher's Britain to explore the intricate world of drug smuggling and distribution. Coogan's character, a former deep-cover operative, assembles a team including Kate (Hayley Squires) and Guy (Tom Burke), who must infiltrate dangerous criminal organizations like the Turks and Scouse kingpins. Despite a strong cast and effective period detail, the show is criticized for being competent but not gripping, authentic but unoriginal, and ultimately feels like a risk-averse production that lacks the distinctive flair of more compelling series.
