For foreign language series, you cannot beat “Salamander” and “Before We Die”. I just finished binge watching both of these and was totally engrossed!
Try the French TV version of Maigret with Bruno Cremer as Superintendent Maigret.
The BBC Maigret series with Michel Gambon and the next more recent version with Rowan Atkinson
turn are pretty good but Cremer owns the character like David Suchet owns Poirot.
The subtitles are clear, the stories are entertaining and there’s none of the self righteous merde American TV shovels out.
