Since the movie plays in real time, the viewer is put directly into the story and feels like the third soldier.

At first, we accept Lance Corporal Tom as the lead character, since he has way more lines then William at the beginning. However, we get to understand that we need to switch to William. This rare in movies and brings a lot of depth and excitement.

The storyline is very simple and easy to follow. We don't question the actions seen on screen, because it is always very clear. This forbiddens the interpretation of the viewer to a certain degree.

The little dialogue helps us to perceive the environment and circumstances the characters are faceing. In return, we only know the main characters superficial which makes it hard to feel deeply connect to them.
