I watched it last night, quite a bizarre film, in the way some French films are, but I don't mind that too much, I found it reasonably watchable, although in spite of a great cast, I'm not sure I'd have been very happy if I'd paid to see it at the cinema, it wasn't good enough for that imo.
I like Olivia Colman as an actress. I've always thought Jessie Buckley a very talented actress, so good in Wild Rose, and also in this film.
I thought maybe the Olivia Colman/Jessie Buckley character was the lost daughter herself, insomuch as JB, alluded in the flashbacks, of her horrible upbringing at one stage and not liking her mother. Although I guess that's open to interpretation.
Did she survive the hat pin incident? she seemed to, again open to interpretation
