This is a subjective topic. So whoever wishes to undertake this topic would have to give a detailed argument as to why a specific feature-length documentary should be part of a top ten.
This Movie Is Not Yet Rated, Waiting for Superman, Super Size Me, and Gonzo would be some good recommendations. – Aaron Hatch9 years ago
Blackfish. Always Blackfish. – Hannah Spencer9 years ago
Miss Representation and Fed Up are also good recommendations. You could also discuss the effect the documentary has, if any. For example, the movie Blackfish caused Seaworld to lose profit. While films like Fed Up and Food Inc. show how the cooperations and government play a role in the public's food, yet no change has occurred. – Amanda Dominguez-Chio9 years ago
