Jamie Jo Mitchell feels too thin here

Looking just at Jamie Jo Mitchell's work as Stunts, there is a clear point of view in the performance. It is not a careless performance, but it feels under-shaped. The work never fully settles into the rhythm of the movie. The performance is functional, but it does not leave much after the scene ends. I wanted more specificity, especially in the emotional transitions. That overall aftertaste is what stayed with me after the credits.
