What I liked most about this show (and why I recommended it) is how it delves into the human psyche and the interactions with it's surroundings when one is placed under mental stress. Although this show touches on solitary confinement and the effects that it has on the individual, it doesn't quite capture the essence for which it is intended.

The very nature of this form of punishment is to serve as a deterrent to prisoners so that they will learn to welcome their newfounded regimented environment and adhere to the rules that go with it.

This story does a good job of capturing the prisoner's complete and utter loneliness that he suffers from as a result of his confinement and his desperate need to interact with others. You see him cling to the smallest of good deeds that one of the guards does for him (which he does out of sympathy, no doubt). And how he rebels against the other guard, who is not so good, and intentionally goes out of his way to try to make the prisoner's surroundings as miserable as possible.
