I feel David Zaretti is not convincing

David Zaretti as Visual Effects Supervisor has some moments that stayed in my mind. I do not hate it, but it did not pull me into the story. The role needs more detail, but the performance stays on the surface. 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. Maybe other people will like it more, but this is my feeling.
