There are documentaries that focus on history, science and important current events, and obviously those are important. We will always need honest and objective filmmakers to educate us beyond the junk we're taught in high school. But there's also a sub-genre among documentaries that might seem slight, but is still important in some small way. I choose to call these the "human interest" documentaries, and if you've ever seen the amusing Spellbound, the very entertaining The King of Kong, or the heart-wrenching Dear Zachary, then you know what I mean. Documentaries that don't exactly cover "earth-shattering" stories, but manage to find a small nugget of universal truth in even the plainest of people.
