Mental Wanderings - Balance to the Force

Another science fiction related query I've had is related to the role of Anakin Skywalker. It was said that he would bring balance to the Force. In my mind, bringing balance to the Force would mean that in some way the Light and Dark Sides would live in a sort of harmony - like the yin and yang. This is not what Anakin accomplished though. His defeat of the Emperor and his overcoming the power of the Dark Side in his own life led to a defeat of the Dark Side and the victory of the Light Side. Therefore, he did not bring balance to the Force, but a clear, one-sided victory of the Light Side.
