It's impossible that doctors would have known about PCOS at this time in history, as that scene with the doctor suggests. This is a very recent discovery (20th century) that received a name even more recently.

It's difficult to side with or relate to any of the leads because they have very conflicting and confusing attitudes and behaviours and I just can't understand them. Rosalie is terrified of Deluc's reaction in the beginning and does everything to "hide" her "affliction" for as long as she can. Then she does a 180 and will not conceal herself anymore, even going so far as displaying herself and profiting as much as possible from the general curiosity, regardless of the emotional costs, to herself or her husband. And while he is awful to her it's easy to see why he would've preferred not to be exposed like that, with his wife becoming a circus act.

The beard was not particularly fetching for me tbh and the ending scene left me dissatisfied.

Otherwise, it's a decently shot period drama.
