Holloman's perspective is self-centred and reflective while Lawrence's is outward and exterior. In this way, no matter what happens to him, Lawrence is sheltered from the effects of the acts while Holloman himself sinks a little deeper into the quagmire.
The film is an interesting look at power placement and control and makes a very definitive statement.
If there were one criticism about this film, it is the length. It is a great story, with great actors, and nicely shot: it's simply too long. The film's message is somewhat masked in its pacing and over-explanation and could benefit greatly if it were tighter.
