Tetsuo Morishita has nice moments but also some problems

For me, Tetsuo Morishita's work in Hatoko no umi (1974) is easy to talk about after watching. 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. There are good moments, especially when the scene is quiet. This is only my personal view, but the performance changed how I enjoyed the film.
