Those are great, I checked them out!
Here are some other good ones, mainly dealing with human consumption/corruption/etc:
These are online, and the first one is only 20 minutes! (The second one, Zeitgeist I and II, are very intense, but have definitely changed my view of the world.)

The Corporation (about corporate greed)
The Beautiful Truth (about healing cancer with whole foods!)
Collapse (a pretty frightening but beautiful political documentary that just came out)
I also liked the recent Michael Moore film: Capitalism, a Love Story. I usually dislike talking or thinking about anything that has to do with money or politics (why ruin a beautiful day?), but unfortunately, money and politics define our current system.
