Overrated Originality

Why are people so concerned with originality today? I recently saw the movie Avatar which was Awesome!! It was a beautiful cinematic masterpiece. Now for the most part people seem to agree with me but I have heard a few complaints. Apparently some people feel that the story wasn't original enough. Now I will admit that the story was reminiscent of Dances With Wolves or Pocahontas. Big bad corporation tries to trample nature loving indigenous people. I have heard it before. You have heard it before. But does that really have to be a bad thing? I can't even count the amount of times I have heard the poor boy (or girl) falls in love with rich girl (or boy) story. I have lost count of the amount of underdog sports movies I have seen. How many Cinderella movies have been made? Good stories get told alot. They get reinvented and retold for different generations to enjoy. Isn't it still creative to retell an old story in a new way? I think it is. I think originality is not the only sign of good art. In an age where everything has been done I think we need to stop being so concerned with originality.
