I feel Brandt Andersen is not convincing

Brandt Andersen as Executive Producer in Dual (2022) made me pay attention more than I expected. 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. For me, it does not feel very real in many scenes. I do not hate it, but it did not pull me into the story. This is only my personal view, but the performance changed how I enjoyed the film.
