Mitsunori Isaki feels too thin here

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