Transformation of Paul

Today the film returns to showing the motif of windows and doors. An example is when Albert was injured. The nurses took him to the surgery room but while taking him there they closed the door on the camera. A depiction that something terrible is going to happen. This technique of closing doors on the camera ive seen several times. Im assuming that this technique originated from this movies. A scene thats buried in my head was the transformation of Paul's opinion of the war. Kantorek teaching his students about how war is about heroism asks Paul of his experience. You see in his eyes the torture, death, and misery he suffered at the trenches. Before he thought of war that its about herosim, bravery, and glory. But this all changed with the first bombardment.
