I feel Duan Chun-hao is not convincing

I watched Long Spirit (2022) and Duan Chun-hao was one of the parts I kept noticing. For me, it does not feel very real in many scenes. Many moments pass very fast, and I do not remember much after them. I do not hate it, but it did not pull me into the story. Some emotions are too simple, and I cannot believe the character enough. Maybe other people will like it more, but this is my feeling.
