I've been watching
Des, an ITV drama about the Scottish serial killer Dennis Nilsen. ITV has a reasonable history of producing this sort of docudrama while respecting the victims and not glamorizing the murderer, and instead examining the impact on people who become involved in the situation--a social worker in the case of Fred West and
Appropriate Adult, or the investigating police officers in
This Is Personal (in which the murderer, Peter Sutcliffe, spends almost all the time off-screen). This one focussed mainly on the police and on the man who wrote a biography of Nilsen, Brian Masters. We got three interlinked and excellent performances from David Tennant (Nilsen), Daniel Mays (Detective Chief Inspector Peter Jay) and Jason Watkins (Masters).
I'm feeling a bit sorry for Tennant, though. Reviewers seem to have become obsessed with his accent. I've seen a reviewer claiming that Tennant "can't do Scottish accents", and another (who had obviously looked up Tennant's place of birth) claiming he was using his "native Scottish accent". He was actually working pretty hard to reproduce Nilsen's characteristic northeastern Scottish accent, often called Doric: you can hear a
sample on YouTube, and it's a long way from Tennant's own rather posh West Lothian accent.
I'm not sure Tennant got it entirely right--he has the Doric lilt, but some of his vowel sounds seem a little low, and the real Nilsen (interviews are accessible on line) had considerably shifted his accent after living in London for a couple of decades. But it was undoubtedly a very good effort.
