You need contrast and conflict in order to tell a story. Stories need to have dark and light, turmoil, all those things. But that does not mean the filmmaker has to suffer in order to show the suffering. Stories should have the suffering, not the people.
David LynchIn my mind it's so much fun to have something that has clues and is mysterious - something that is understood intuitively rather than just being spoon-fed to you. That's the beauty of cinema, and it's hardly ever even tried. These days, most films are pretty easily understood, and so people's minds stop working.
