I feel Michael Masini is not convincing

Michael Masini as Peter Ohl has some moments that stayed in my mind. The role needs more detail, but the performance stays on the surface. 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. Many moments pass very fast, and I do not remember much after them. Maybe other people will like it more, but this is my feeling.
