I'm not French, Dutch or from Belgium - so I could care less about the accuracy of their accents. As someone who is obsessed with true crime documentaries, I was not familiar with this case at all. I am fascinated and completely gripped by the story. I would ignore all those other comments irrelevant to the entertainment factor. This is a very cleverly written and executed mini series. Of course I immediately researched the actual crimes and The Serpent/Bikini killer and it was surprisingly accurate. If you like true crime genre- this is a must.
