International Harry Potter Trailer

I found this "International" version of a trailer for "Harry Potter and the Half-Blood Prince".



Why do we always get dumbed down versions of books, trailers and movies in the U.S.? Why do we stand for it? It is so annoying. But I guess the people who are responsible for these things are right- we never protest that things have been dumbed down or made less complicated or more violent for our viewing benefit. I just don't get it...sigh.
