Well, this a bit awkward. A fortnight ago, in my last TV column, I confidently asserted that, despite the involvement of Jed Mercurio, Bloodlands (BBC1) was nothing like the programme it was being compared to in all the advance publicity. Two episodes, several twists and at least one bent copper later, my ringing conclusion ‘Just don’t expect Line of Duty’ feels somewhere between premature and spectacularly wrong.
