First episode is good because it deals with known facts, but it goes rapidly downhill when they run out of actual evidence. From then on it becomes more and more ridiculous in its efforts to come up with something, anything vaguely new or relevant to the investigation. There are so many ifs, buts, maybes and possiblys that it becomes laughable and you realise what a con this series is. There is nothing here that hasn't been revealed before and the whole thing is stretched so thinly with filler and red herrings that it loses all credibility before you get half way through. Hopefully the case will be solved some day, but this doesn't get close.
