It doesn't get any better than this. One of the all-time-great TV dramas. Politics, sex, betrayal, government chicanery, Big Oil shenanigans, more betrayal, more sex, intrepid reporters and the drollest news editor ever to grace the small screen. It all begins with a murder and a suicide. Then the suicide becomes a murder and we're off and running.
Be warned. The pace is break-neck and the dialogue sizzles. Unless you know Brit-speak, use the sub-titles. Repeat viewings are compulsory. Watch this six-part BBC series first, before the Hollywood remake debuts next year and ruins everything.
