Benjamin Nowicki has nice moments but also some problems

I watched Dunkirk (2017) and Benjamin Nowicki was one of the parts I kept noticing. I wanted more detail, but it still has some useful emotion. Some parts are good, but other parts feel normal and not very fresh. There are good moments, especially when the scene is quiet. I can understand what the actor wants to do, but not every scene is strong. I remember both the good parts and the parts that did not work so well.
