1. A good film may appeal to the masses, it's doesn't HAVE to be a contradiction. Correct me if I'm wrong, but what we witness right now is absolute dullness as a result of EXCLUSIVELY trying to repeat former successes.
2. This justifies the equation 'a mainstream film is a bad film'. Exceptions only prove the general rule.
3. Spielberg, who now complaints in a chorus with Soderberg and Lynch, contributed to the misery. He is a master of the big budget movie as well as of the serials, franchises and remakes. And he is responsible for quite a bunch of terribly stupid movies.
4. So maybe Lynch has lost it. I don't know, but I accept that creative people can burn out too. Their work survives. If not for the masses, then the more for few. Rock'nRoll (cinema) is bigger than all of us ...
