Some of the movies that I found quite entertaining:
* Meat the Truth
* Poison on the Platter
* What in the World Are They Spraying
They have to do with global warming, GM food, multinationals, manipulation etc. They all are very tendentious, keep your critical thinking switched on and perceive it as entertainment. I am sure I will find out more informative stuff. All movies can be watched in topdocumentaryfilms.com either in Environment or Health sections. Well and if you are interested in animal protection, watch Earthlings.
