Oliver Stapleton has nice moments but also some problems

For me, Oliver Stapleton's work in Birthday Girl (2001) is easy to talk about after watching. It is not too loud, but I still remembered the performance after watching. There are small expressions that make the character feel more real. I think this work helps the movie a lot, even when the story is busy. The acting feels natural, and I can follow the feeling very easily. I remember both the good parts and the parts that did not work so well.
