Whenever you see this type of "let me put myself in their shoes" documentary, always be cautious. This is a pretty good episode of 30 Days in that it gives those who've never been, a good look into what Jail (not Prison) is like. The downside, of course, is that we don't really get to see the lives of the inmates once they've served their sentence. That, of course, is an important element. Unfortunately, it's missing here. Knowing that this show fails there, however, can help you enjoy it for what it is.
