“Roger & Me”
“Bowling for Columbine”
and
“Fahrenheit 9/11”
I’ve also seen Gore “An Inconvenient Truth” and dare say, when Crichton wrote “State of Fear” I know which fear machine he’s talking about.
I’ve also seen “Supersize Me” quite good. And “Cadillac Desert” both book and PBS DVD. IMHO, they should be mandatory reading for anyone living in the Mountain and Pacific time zones.
As another pointed out, the bulk of the stuff running on PBS under the brand names “Nova” or “Nature” blow Gore away. Take a look at “Saved by the Sun” from Nova. It’s a look at global solar power options, through individual cases. Or take a look at PBS’ covering of the history of credit cards “Secret History of the Credit Card”.
PBS does better documentation without the conspiracy overtones, IMHO.
