First off, watch it in the original French with English subtitles. You'll thank me later.
The show is a very good take on the classic French gentleman thief Arsène Lupin. The show has excellent casting, good story, and great sequences. I am sure the second part coming out in December will not disappoint.
Not quite sure how historically accurate it is but it makes for a very good TV show binge (as are most Netflix originals). Story line is superb and the ending was a killer. Favorite character: Thousand Eyes (that mofo is ridiculous for learning mantis style with just one encounter!!!)
