What's your beef? The casting? The idea of another re-make? Both? I think if you look closely re-maes generally aim to add another layer of meaning to the original story, or bring into the foreground one or more of the other characters. As Disney generally treats the enduring myths of humankind in its films, it would seem to be perfectly reasonable for these universally compelling films to be periodically updated in line with modern audiences who happen to have been born after the original production.
