Rio Sawada has nice moment but also problem

For me, Rio Sawada in Stage 『The Summer Hikaru Died』 (2026) is around 6.5/10. I wanted more detail, but it still have some useful emotion. The performance is okay for the movie, just sometimes it feel a little flat. There are good moments, especially when the scene is quiet. Some part is good, but some part also feel normal and not very fresh. I think the score is fair because I remember both good part and weak part.
