5 Stars for the drama, 1 star for the way Netflix have botched the subtitles.
Just a note to the translators. a subtitle like "Guards talk excitedly in Romanian" (yes, a real subtitle) does not count as translation, especially when it's part of the plot.
There is no option to translate only the non-English dialogue so subs are either on or off, & even with my schooldays knowledge of French I could tell the translating was just shoddy & missed crucial plot points,
I know the Americans are not keen on subtitled programs but this is top British drama so Netflix please get it sorted !
