Lee Yun-jae is okay but not always strong

Lee Yun-jae as Production Sound Mixer in Start-Up (2019) made me pay attention more than I expected. Some parts are good, but other parts feel normal and not very fresh. There are good moments, especially when the scene is quiet. I wanted more detail, but it still has some useful emotion. The performance is okay for the movie, but sometimes it feels a little flat. Maybe other people will like it more, but this is my feeling.
