What did people think of this film?
Personally I thought it did a good job getting the basic science right and making it understandable for the average person. The parts about Al Gore weren't really necessary, but probably made it more watchable for the general public. It did get a few details wrong and wasn't specific enough in some places, but overall I thought it was a good introduction to the science.
There's also the controversy about showing the film in schools. Personally I don't think there were any errors significant enough to make it inappropriate for showing in schools, and an accompanying explanation of the minor errors is probably a reasonable compromise.
