I feel Shea Kelly Benezra is not convincing

For me, Shea Kelly Benezra in Palm Trees and Power Lines (2023) is around 3.5/10. Some emotion is too simple and I cannot believe the character enough. For me it does not feel very real in many scene. The role need more detail, but the performance stay on the surface. I do not hate it, but it did not pull me into the story. Many moments pass very fast and I do not remember much after it. This is only my personal view, but the performance change how I enjoy the film.
