I feel Thomas Krag is not convincing

Thomas Krag as Additional Editing in Dogville (2003) made me pay attention more than I expected. 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. For me, it does not feel very real in many scenes. This is only my personal view, but the performance changed how I enjoyed the film.
