You can defend all the equipment and RED cameras that you want to defend... But I guarantee you that if Tarantino or Nolan or Paul Thomas Anderson started shooting on digital their films would lose a weight to them. The best of the best know what medium has soul to it. There's a reason they are where they are.
David Fincher has done some great things with the RED cameras but my favorites of his are still Seven and Fight Club. Which were both shot on film. Call it a coincidence or like you said about the writing... how it's about the substance... but I think that after all is said and done there's much to be said of the organic and there always will be.
Everyone on this site will hate my comments because they likely use a 7D, 5D, GH3, GH4, etc... But I stand by my opinion that there's soul in the old tools.
Just call me a record collector in the world of ipods and mp3's I suppose.
LOTR was shot on film. Which is immersive and feels like a window into the story.
The Hobbit was shot on digital. Which is not immersive and is like a simulation.
Digital is easier and requires less human effort which creates less human of an experience for the viewer. In my opinion anyway.
The medium is the message.
