If films, uniquely American films, are part of our society's cultural heritage then he is not only changing or rewriting history but doing a great disservice.
If he in the past talked about the altering of films and how evil it was why is he doing the same thing. I see no difference in him being the creator, because he is also the studio media mogul and not just the artist. No difference at all between him or the studios he rightly demonized and criticized.
