Cordelia Levinson did not work for me

Cordelia Levinson as Nadja has some moments that stayed in my mind. For me, it does not feel very real in many scenes. The role needs more detail, but the performance stays on the surface. Some emotions are too simple, and I cannot believe the character enough. I do not hate it, but it did not pull me into the story. Maybe other people will like it more, but this is my feeling.
