I agree with those that write in their reviews that the first three episodes are compelling. These have a lot of suspense, the actors are excellent, in particular Keeley Hawes and Sophie Rundle, and the storyline is intriguing. However, the second three episodes, which is the series' second half, is as if there has been no thinking ahead regarding the end of the main storyline. The scenes with the Bodyguard in his bomber jacket are far too long. The worst part is however the final ending, since although it is surprising, it makes no sense at all. Nadia has been lying the whole series and has been making bombs and distributing them while in jail. How? On top of this, this story does not really have a theme. And this while taking as the protagonist a bodyguard was such a good choice.
