Review by JohnC-6

This is not your average spy thriller: it's mainly talk, tons of it, between a small group of British intelligence employees who all seem to live their personal and work lives in each others pockets and beds. To attempt to add gravitas to the production, the colour has been desaturated and the light dialled down to dull and grim, so viewers know it's a serious drama, not James Bond.

There are a few effective action set pieces to keep viewers awake ( not my wife, unfortunately, she slept through most of it ) but not really enough, I'm guessing, to satisfy the action fans.

For film fans who try to see everything that opens in cinemas, only.
