I guess I'm a bit of a purest, no make that I'm alot purest, I think a work of art, be it film, video, music, book, or painting should be left as the creator left it when he/she was finished with it.
One could add color to the Universal classics, or clean up the edges in Harryhausen's movies, or add sound to silent fims, or any number of other things to make the movies pop to draw in new fans, or update them.
No matter the movie, book, song, painting or whatever....I say leave it alone.
That doesn't mean that I'm against a remake of a movie or a band covering a classic song. But leave the original alone.
