I feel Hollie Buhagiar is not convincing

Hollie Buhagiar as Original Music Composer in Punching Bag (2025) made me pay attention more than I expected. I do not hate it, but it did not pull me into the story. The role needs more detail, but the performance stays on the surface. Many moments pass very fast, and I do not remember much after them. Some emotions are too simple, and I cannot believe the character enough. For me, it does not feel very real in many scenes. I remember both the good parts and the parts that did not work so well.
