I loved the documentary, but...

The ending to Jodorowsky's interpretation of Dune is a fascist, totalitarian wet dream.

Paul gets killed, and his spirit takes over the body of everyone, transforming the planet into some kind of green ball of planetoid hypnotist that flies through the universe doing to planets what Paul did to the people.

Gone is every ideal of individuality. No, the only way to be an individual is if you are like Jodorowsky's vision of an individual. If not, then you are an acceptable piece of collateral damage that is only standing in the way of "progress".

For a man who obviously prides himself on his creativity and own sense of individuality, Jodorowsky is surprisingly antagonistic to anyone not like him. Just look at the scene where he describes how Trumbull treated their meeting. It could be seen as Trumbull is a professional who has his eye on the technical details of everything in his life, not letting small things past him. That's not the kind of person Jodorowsky wanted to work with, which is fine. If he doesn't want to be around people who obsess with the details at the expense of the larger vision, then he really should go and hang out with Dan O'Bannon. But when he writes a film that comes to the conclusion that if you are not like Jodorowsky or Dan O'Bannon then you should be replaced (and there's nothing you can do to stop it because they will force you to accept it no matter your wishes), then that's scary.

I really wish the movie had been made (with his ending). I would love to see it completely. It would be weird and possibly wonderful, but it would leave an awful bitter aftertaste once the implications of the ending settled in.
