I was willing to suspend my disbelief with a cop being flown onto a nuclear sub on patrol, and for the rooms on the sub to be surprisingly open.
However. after 2 and a bit episodes I got fed up, as the series just seems to be trying to juggle too many stories at the same time. It feels like a submarine version of 'Line of Duty' and not just because of the same actor appearing in it. Whilst I really enjoyed that series, I just can't get on with this one. I just wish that it had kept things a little less convoluted.
For a truly great crime/political drama , Edge of Darkness (the BBC series from the 80s, not the movie) is possibly the greatest of it's kind. Anyone who hasn't seen it, I urge you to do so as it's a brilliant programme and just as relevant today as it was back then.
