Some films and some filmmakers don't do popcorn movies, and the great Stanley Kubrick is one of them. Apparently Kubrick was an Aspie himself, if you read about the man and listen to people who have worked with him it all makes sense that he was on the spectrum.
Besides the beauty of all his films, and the dark underdone he had towards humanity, they are mesmerizing and fascinating at the same time, yes they are slow but never boring, yes they are different that any other films and that is because they are art pieces more than perfectly calibrated money making films.
Another filmmaker similar to Kubrick was Andrei Tarkovsky.
Anyway, I think my favorite Kubrick films are : Clockwork Orange, Full Metal Jacket, Lolita, 2001 and Dr Strangelove.
