I watched this because my favourite French actress, Audrey Fleurot stars in it and she's magnificent as the tormented flame haired heroine Adrienne. However, all the cast are fantastic, the period detail and costuming excellent and the horrific fire scene in the first episode, which happens in real time, devastating, upsetting and thrilling all at once. The story is a fin de ciecle tale of the rich and the poor set in Paris and filmed in some the most beautiful houses I have ever seen on film. The story is a "page turner", well paced, gripping and with characters you care about. I wanted all the women whose stories are told after the dreadful fire, to have happy endings. If you are looking for a French "Downton Abbey" this may be a bit gory and there are a few tasteful sex scenes although minimal nudity. The 18 certificate is presumably for the injury detail after the inferno, which is pretty grim. I watched the whole 8 episodes in two sittings. Recommended for anyone who likes bodice ripping historical drama although this series did have a feminist twist, most of the men either being weak or hissably villainous! Overall, extremely good Gallic drama with very high production values. 9 out of 10.
