Those are different than movies. As far as movies go, Hollywood is right, "good" is mainly defined by the viewer, so since everyone is different, it's really difficult to put the "good" label on anything. So the only real way anyone can judge a movie compartively to another unbiasly is by its popularity, which in this case equals how much money it makes.
Haha, i did notice that, but then I realized that was necessary. Bruce Wayne is a multi-billionare, people know him. They would recognize his voice. He has to disguize it.
