Sergey Glushko feels too thin here

Looking just at Sergey Glushko's work as Actor, there is a clear point of view in the performance. The work never fully settles into the rhythm of the movie. It is not a careless performance, but it feels under-shaped. Several choices feel too broad for what the scene seems to require. I wanted more specificity, especially in the emotional transitions. My reaction is mainly about this specific film, not a judgement on the performer overall.
