I feel Pitawat Pruekkit is not convincing

Pitawat Pruekkit as Tee in Game Changer (2021) made me pay attention more than I expected. The role needs more detail, but the performance stays on the surface. 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. 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.
