Michael Moore has in the past made a large number of very highly respected documentaries, indeed he has won awards for some of these. As such, as latest the Planet of the humans was highly anticipated by many people.
This is not meant to be a full review of the documentary, as there have been many far more qualified people who have already done this. I am really going to highlight the problems and suggest that you look at them yourself and be fully informed when you are engaged on these by climate change deniers.
