I feel Samuel Kishi is not convincing

I watched The Wolves (2020) and Samuel Kishi was one of the parts I kept noticing. 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. For me, it does not feel very real in many scenes. The role needs more detail, but the performance stays on the surface. I remember both the good parts and the parts that did not work so well.
