First of all I have to say that I have no criticism, whatsoever, of this series. I am a student of the French Language so I recommend watching it in French with sub-titles, as watching it dubbed loses more than half of the atmosphere.
This is a fictional tale set in the aftermath of a genuine event of 1897 when there was a huge and terrible fire at a charity event in Paris which claimed the lives of 125 people, most of whom were aristocratic ladies. The story revolves around the lives of three women who survived the fire: one unscathed but affected, one badly burnt and disfigured and one who is uninjured but................well! Wait and see.
The drama is set in Paris in 1897 and the producers have done a great job of capturing the atmosphere of the city and the era, the attitudes of the people and the relationships between the different sociopolitical groups. The dramatic pace of the series is well maintained and there is a certain degree of "cliffl hanger" at the end of each episode, to the extent that I will admit that I was forced to "binge" watch it.
The plot is relatively simple but with a few twists and turns in a rather "Dickensian" fashion which results in a nice classical structure of having a beginning, a middle and an end. However, it is not without some excitement and a fair amount of tension. OK! So some will say that the ending is predictable, so what! I loved it.
The "18" rating is totally unjustified and the description "strong sex" has obviously been applied by a Sunday School teacher who has yet to experience sex of any kind. There is, perhaps, a view of one or two female bottoms & one nipple. but that's all, although there is some rather tender, and carefully edited, lovemaking.
I rate this as a thoroughly entertaining piece of drama, well worth watching. It is well acted and extremely well produced with good scenery and atmosphere. Overall I was left feeling happy and glad I'd watched it.
