Not in "French"? What were they thinking?!?
With so many successful Scandinavian tv-series (Borgen, Wallander, The Bridge, The Killing, ...) in original language, here we have a French monument - produced by the French - being played in English?! WTF? This is the stupid 'The Man in the Iron Mask ' all over again? So what, there are not enough good French actors available? Is this meant to educate English-speaking teenagers, who don't like to read subtitles? This is a purely opportunistic choice from the makers who rather bet on 'demographic' assessments than on the artistic value of the series. Pathetic!
ps: I am not speaking French and do not live in France.
