I'm sorry, but I don't have time to watch a 41 minute video right now, so I can't comment on this film. On critical thinking and 'alternative' beliefs, though, there is one point I'd like to make that I don't often see made. It's what irritates scientists about pseudo-science; this is different from what irritates many outspoken skeptics who don't actually work on science themselves. (For some scientifically orthodox skeptics, their viewpoint really is just another irrational dogma, defended emotionally.)
Suppose you read about some scientific theory and think, "How are we supposed to know that things are really that way, and not this other way I can think of?" Some trusting souls seem to imagine that scientists have some easy way of dismissing questions like that. Nope. If the theory really is established, then your question and many more like it will have been exhaustively researched, possibly for hundreds of person-years in total. There will be really good reasons, based on plain facts and common sense, why we can be sure that your alternative idea is wrong.
But it may be a long story. Hundreds of person-years of painstaking work may not fit into a soundbite. So the only short answer to your question may be, "We know." Of course, that would also be the short answer you would get if a club of white-coated hierarchs had simply voted, between puffs on their cigars, to dismiss your idea. So people who don't have any idea how much work really goes into science tend to think it must be more like that. But it's really not. It's a huge amount of hard work.
So scientists don't really hold it against pseudoscience that it happens to be wrong. Working scientists investigating fresh hypotheses are wrong almost all the time. That's how we make progress, by proving ourselves wrong, time after time after time, until we can't do it anymore. We don't defend our theories; we attack them with every dirty trick we can dream up. The scientist who publishes a clever disproof of a popular theory gets the loud applause. Newton became famous by shooting down Aristotle, and Einstein became famous by shooting down Newton. Science is a brutal line of work, and being wrong is like bleeding. Happens all the time. Deal with it.
What scientists hate about pseudoscience is that it's lazy, and it avoids hard testing because it's afraid to bleed, and yet it makes money and gets attention by trading on the real work and courage of others.
