There do not appear to be many reviews for this. I will add mine, though I am currently half way through. I have seen enough to pass my opinion.
It's a quality production, no mistake. Someone has criticized various plot points and minor inconsistencies, i.e. Accents.
Get past these, and a few cliches, and you won't be disappointed. I've seen a couple of continuity goofs, things in the wrong hand, etc; these are trivial.
The two leads appear formulaic, with their demons, etc - but these add to the drama. The casting is very good, throughout the team (the crime squad).
The storyline hints at The Manchurian Candidate, or even the Bourne series, quite early on. Film and fiction buffs will find some character names amusing; Moreau and Bergeron are giveaways!
Make no mistake, it has some very unpleasant themes, and scenes; if one knows this territory, this is to be expected.
Whatever transpires, the performances of Decker and Elbaz would be worth revisiting.
