Kim Yong-su is okay but not always strong

Kim Yong-su as VFX Supervisor in My Heart Puppy (2023) made me pay attention more than I expected. There are good moments, especially when the scene is quiet. I wanted more detail, but it still has some useful emotion. I can understand what the actor wants to do, but not every scene is strong. The performance is okay for the movie, but sometimes it feels a little flat. Some parts are good, but other parts feel normal and not very fresh. This is only my personal view, but the performance changed how I enjoyed the film.
