What's wrong with colorizing black and white films? Have you seen Night of the Living Dead in color? It's fantastic. Like they actually filmed it that way. I honestly can't wait until they get around to doing Psycho. I suppose we just have different tastes. When I go to see (for example) the Star Wars movies, I expect to see two people swinging bright, glowing blades at each other, not two people swinging bright, glowing blades at each other behind a thin screen of filth. I say remove all the grain, be it from the negative or wherever. Grain, unless intentionally inserted, is an imperfection in the film-making process. Any engineer would tell you that the best way to improve a process is to remove its imperfections. All the cinematographers in the world can deny this, but they'll just look stupid. Bright colors and the absence of grain may not be "artistic," but they're cleaner, and to the normal movie-goer, that makes a much better impression.
