Terrific drama, beautifully performed and well-paced. I notice that a previous reviewer suggests that the series avoided 'points scoring and let events speak for themselves', but I beg to differ. There were, in fact, any number of 'right-thinking' lectures in the episodes, which were rather patronising. It is perfectly possible to be proud of established British culture without choosing violence or extremism. The closing titles were a perfect example of Disraeli's 'lies, damned lies, and statistics'. It was meant to reinforce the writer's view that 'far-right' terrorism is a threat greater than Islamic radicalism, but that argument would be shown to be nonsense in a detailed discussion.
