This show, like so many other British TV shows, uses a conspiracy involving members of some security forces in its principal plot. It’s an oft-repeated plot.

Secondly, the personal lives of several characters have no bearing on the plot, so their purpose seems to be only to fill the time.

On the plus side, this is a serious TV show that concerns itself with a very real problem in Britain.

I watched this primarily because Nicola Walker is in it and she never disappoints. As much as I loved her in River and Unforgotten, it’s was refreshing to see her play a non-detective in a police show detective (she was brilliant as a perpetrator in another series).

This series has a lot of moving parts so you shouldn’t be distracted as you watch it. Another review states that personal details of some characters seem to be included as filler, and who I knows I of it is true, but I often find these shows or movies about conspiracies easy to predict in some of their details, but whether it was intended or not, the moving chess pieces kept alive so many possibilities I found i didn’t know where aspects of the plot were going.

So I found it to be entertaining. My only wish is that a couple of the characters did quite get what I thought they deserved.
