Had this been a fictional drama I would have given up long before the last episode. I had never heard of this case and it was a fascination that kept me going. While the acting from the leads is good I couldn't care for anybody in the show. The worst part is certainly the time devoted to the kids. Not sure why (probably the writing) but they added absolutely nothing to the story. It was also hard to understand why the French editor would have been remotely interested in Firth's character. It was also frustrating that the show gave us seemingly plausible alternative methods of death/murder but never followed them up. I wish I had watched the documentary instead but not sure I can invest too much more time on this story so will probably just wiki it.
