RJ Siu never quite convinces

Looking just at RJ Siu's work as Grip, there is a clear point of view in the performance. 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. It is not a careless performance, but it feels under-shaped. Several choices feel too broad for what the scene seems to require. Different viewers may value it more, but for me the effect was limited.
