I feel Dallas Hartman is not convincing

For me, Dallas Hartman's work in Roommates (2026) is easy to talk about after watching. The role needs more detail, but the performance stays on the surface. For me, it does not feel very real in many scenes. 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. This is only my personal view, but the performance changed how I enjoyed the film.
