The Bureau (French) is very good indeed. It’s about the French secret service and is set in Paris, Algiers, Syria & Iran and who knows where in series 2-5. Each series has 10 episodes. It’s also very hard work to watch with dense and complicated plotlines and reading subtitles though I’m used to those. It’s definitely not something you could watch without full commitment. I am enjoying it.
One good thing about watching programs with subtitles which I first started to do in 2010 is that it got me out of my bad habits like looking at my phone, eating or whatever which meant I often lost concentration watching English programs.
