Its pure escapism and we all need a bit of that sometimes. I don't get why everyone wants tv dramas to be so realistic all the time. A bit of far fetched does you good. There are some brilliant actors in this, Best, Challenor and Mills are great to watch in anything anyway but the storyline is interesting and takes a few twists and turns. The sideline characters had to want becomes a very complex plot and it keeps you guessing who is telling the truth. In parts it could very well happen in real life but yes there are minor inaccuracies and loopholes because it's fiction. Watch it for entertainment value and it will deliver. If you want reality watch a documentary.
