Fiona Chaffey is a bit weak here

I watched The Snowman (2017) and Fiona Chaffey was one of the parts I kept noticing. Some emotions are too simple, and I cannot believe the character enough. Many moments pass very fast, and I do not remember much after them. I do not hate it, but it did not pull me into the story. The role needs more detail, but the performance stays on the surface. For me, it does not feel very real in many scenes. Maybe other people will like it more, but this is my feeling.
