I feel Semen Bely is not convincing

For me, Semen Bely's work in Ледяная история (2021) is easy to talk about after watching. For me, it does not feel very real in many scenes. 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. Many moments pass very fast, and I do not remember much after them. This is only my personal view, but the performance changed how I enjoyed the film.
