The story-telling was extremely laboured and slow and I found myself getting really bored. The structure is extremely poor with timeline pinballing which I think hampers the character development and perhaps how their crimes evolves.
The actors, in general, were passable, Jenna Coleman is quite good, however, Tahar Rahim who plays the role of Charles Sobhraj was extremely flat and one-dimensional. In no way helped by the backward and forward jumping in the storyline.
The previews were a lot better than the actual mini-series.
