No, Johnyboy--this whole issue is framed in terms of YOUR humble opinion. Maybe grain should be erased and maybe brush strokes should be erased--in your opinion. For you, that is a preferable aesthetic. But why should your preference dictate how everyone sees it, or how the art, irrespective of ANYONE'S preference, should be presented. Instead of appreciating what the art IS we want it to be the way we want it to be. But why is your way "the best" way or an "improved" way? You open up a slippery slope that ends in a kamikaze dive-bomb. Maybe to me the best presentation is that everything should be presented in green tint, and have Pikachu from Pokemon somewhere in the frame because he's awesome; "everything can be improved." Maybe every film should be fullscreen, because this is how I prefer it, and maybe all black and white movies should be colorised, because this is how I prefer it, and maybe all silent films should be dubbed into sound, because this is how I prefer it.
And maybe all movies should end happily, because I hate sad endings, and maybe challenging messages should be edited out because I don't like to think too much when I watch movies, and maybe there should be comedy in every film because I find comedy most entertaining of all and films are designed to entertain above all else.
These arguments are illusions because it doesn't matter what I want or prefer. Films are what they are, and films are made on film, they have grain because they are made from silver halide crystals that react to light, they have flares because they are photographed with tubes of glass, they have bad acting and bad special effects sometimes because of the limitations of the skill of the players involved, and often they are made in ways in which we would prefer they be made differently. You have to respect what they are, not what YOU wish they would be.
They are objects that were created by people at a certain point of time and stand as artifacts of that effort across that point in time. They are what they are, not what you think they should be. Its this infection of this "me" generation that thinks everything should cater to them that is destroying the medium.
