I feel Matthew Suwalski is not convincing

I watched Mad Hot Sweat (2026) and I think Matthew Suwalski's work as Sound Guy is 2/10. The role need more detail, but the performance stay on the surface. I do not hate it, but it did not pull me into the story. For me it does not feel very real in many scene. Some emotion is too simple and I cannot believe the character enough. I think the score is fair because I remember both good part and weak part.
