Franco Nero is a bit weak here

I watched The Man from Rome (2022) and Franco Nero was one of the parts I kept noticing. For me, it does not feel very real in many scenes. The role needs more detail, but the performance stays on the surface. 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. 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.
