Yes this was a brilliant drama, with superb acting as you’ve said. Didn’t you watch the documentary? I think it was on the following night, it’s unbelievable how much the actors resembled the real life families.Just binge watched all 3 hour long episodes of the BBC Drama Four Lives on the BBC I- Player.
A true story, showing the ineptness of Barking police in tracing the murderer of four gay men in 2014.
Starring Steven Merchant and Sheridan Smith, its a gripping, well acted drama that shows that when the BBC move away from the dross of their realty and light "entertainment" programmes, they are still the best for releasing gritty well acted dramas.
I thoroughly recommend it.
