David E. Diano is a bit weak here

David E. Diano as "A" Camera Operator in 21 (2008) made me pay attention more than I expected. Many moments pass very fast, and I do not remember much after them. Some emotions are too simple, and I cannot believe the character enough. For me, it does not feel very real in many scenes. The role needs more detail, but the performance stays on the surface. I do not hate it, but it did not pull me into the story. Maybe other people will like it more, but this is my feeling.
