"Edge of Darkness" continues to be well regarded to this day. When it was repeated on BBC2 in 1992, Sean Day-Lewis wrote in "The Daily Telegraph", “"Edge of Darkness" is a masterpiece. It is one of those very rare television creations so rich in form and content that the spectator wishes there was some way of prolonging it indefinitely". Andrew Lavender, writing in "British Television Drama in the 1980s", has said that "Edge of Darkness" "captured the spirit of its age but went far beyond the drama of its time. [...] It pushed against expectations attaching to the thriller form, often transcending the limits of the genre". Fred Inglis, in his analysis of the serial in "Formations: 20th Century Media Studies", takes it "as one of the most remarkable works of art made for British television". According to Lez Cooke, in "British Television Drama: A History", "In a reactionary climate, when the possibilities for the production of 'social issue' drama were limited, "Edge of Darkness" proved that, by adapting to changed circumstances and adopting a serialised thriller format, it was still possible to produce ambitious and progressive television drama in Britain in the mid-1980s", a view echoed by Sean Cubit in "EcoMedia" who notes that "the series neatly echoed the chill that descended on radical politics in the Thatcher years in the United Kingdom". The television historian Andrew Pixley has described the series as "possibly the finest BBC drama ever made" and "one of the few television programmes where every element can be said to have worked to complete effect"; John Hartley, in "Tele-ology: Studies in Television", called it "the best police drama series ever made for television" and said that "its method of investigative drama can unravel some of the complexities of public life more truthfully than investigative journalism".
