Patricia Rozema did not work for me

For me, Patricia Rozema's work in Mouthpiece (2019) is easy to talk about after watching. Some emotions are too simple, and I cannot believe the character enough. For me, it does not feel very real in many scenes. Many moments pass very fast, and I do not remember much after them. The role needs more detail, but the performance stays on the surface. Maybe other people will like it more, but this is my feeling.
