I have sat through five episodes, and all of them have followed a similar pattern. For about forty minites, our main protagonist, Lana, has some dull and inconsequential discussions with some very average actors. Then, as the viewer is about to nod off, a bomb appears on the scene. These crescendos have some entertainment value, but the characters and plot are so thin that very little seems to be at stake.
It is hard to escape the conclusion that TP is a missed opportunity for ITV. In the right hands, the concept could have made for a compelling show with a relevant political backstory.
