Roselyne de Nobili has nice moments but also some problems

For me, Roselyne de Nobili's work in Un cœur de femme (2019) is easy to talk about after watching. The performance is okay for the movie, but sometimes it feels a little flat. I wanted more detail, but it still has some useful emotion. I can understand what the actor wants to do, but not every scene is strong. There are good moments, especially when the scene is quiet. I remember both the good parts and the parts that did not work so well.
