(Series 3) Irritating switching of timelines (which was ok in series 1) became difficult in this series. Mahershala Ali's acting is laughable, especially when portraying his older self. He does a cringing caricature of an old person what with his bent leg walk and wandering gaze and, quite frankly, no more than 50% of his dialogue is understandable. None of the characters are at all likeable apart from perhaps Stephen Dorf's. A ridiculous plot relating to Ali's wife made no sense at all and added zip to the overall story. Is it really likely that the wife of a detective would be permitted to write a book on the case her husband is working. Really?? Made it all so difficult to watch and then the sucker punch of an abysmal Deus Ex Machina ending. Uuuurrrggghh!
