I feel Angela Ortner is not convincing

Angela Ortner as First Assistant "B" Camera in Bit (2019) made me pay attention more than I expected. I do not hate it, but it did not pull me into the story. Some emotions are too simple, and I cannot believe the character enough. For me, it does not feel very real in many scenes. The role needs more detail, but the performance stays on the surface. Many moments pass very fast, and I do not remember much after them. Maybe other people will like it more, but this is my feeling.
