I only watch the first season, so the comment below only applies to that: The plot seems interesting at first, but the script is so bad that the series ends up falling in quality to each episode. There is no character development. Everyone is empty and boring, and it's hard to care about any of the characters. The relationship between the main characters, Sandra and Paul Maisonneuve, is simply ridiculous. The script tries to force a relationship that simply never happens. The two behave like strangers throughout the entire series and although a past story is quoted it has no ability to create a true relationship and the two characters spend the whole series being boring and distant. The script is very bad. There are no words to describe how bad it is. French police act like a bunch of retarded people in every episode and the way detectives make the discoveries is simply laughable. Most of the time they simply guess things without any evidence. The acting is very bad too. I just watch the series because I'm studying French and I wanted to have a greater contact with the language and the French culture. But I would never recommend this series to anyone. It's just bad.
