1--it is clean (no language, no nudity...BoBB has quite a bit of both, and while they are in context, they are still bothersome for many viewers).
2--the film features interviews with a broader range of people, ranging from experts to random people on the street.
One quote (played during the credits, so I don't know who said it) was particularly memorable:
We can only change things in two ways: either with litigation, or with education.Obviously, I'm a proponent of the latter.
While this movie does have its flaws (it gets pretty dramatic--in melodramatic way--at the end; and they don't provide references for most of their statistics, so I don't know how precisely factual they are), it's still an effort at education, and for that I must applaud them...at least a little bit.
