Context: I'm a French leftist who loves Europe (more than France even) but hates what the EU has become. I believe Brexit is a bad thing for the UK but a good thing for the EU, and that other countries that don't share the ideals of Europe (Hungary, Poland, Italy, maybe Austria, the Czech republic) should also leave. The remaining countries would then become a federation with a single passport, a single army, the same laws and rights everywhere, and a common environment-friendly humanistic dream. Nationalism has no place in Europe. I would not be surprised if the EU had taken a much better path if the UK had never been part of it. I believe the UK is corrupted by money and special interests, like the US. The focus on money is what has ruined the EU and why citizens have come to hate Europe. As I said, I am a leftist, so no big surprise here.
As for the documentary, like another reviewer, what strikes me the most in this documentary is the absolute mediocrity of the people that are presented to us, who behave more like high schoolers than like world-class diplomats and negotiators. I have been lucky enough to work with world-class American intellectuals for a few years and nobody in this documentary comes even close to being a world-class mind. The worst of the bunch is undoubtedly Guy Verhofstadt himself, who appears nothing less than simple minded, with awful humor and naive thinking. Michel Barnier is the only person who is not completely ridiculous, without being that impressive either. World diplomats must be laughing when they meet such mediocre European officials. In fact Theresa May is the only person in the documentary that seems strikingly smart. Not as smart as Trump, of course, but who is?
If you want to be ashamed of being European, watch this documentary. I am surprised that the people in this documentary did not see how embarrassing it is for them. They may even have thought that they looked cool somehow. Poor them, and poor us.
