What the drow actually look like, is in my mind immaterial. The case will be made while most people will yet have seen the movie. Most of the people that jump on the bandwagon will have done so, while not having seen the movie. It has been so for every controversial movie of my lifetime, as far as I can tell, going back to the Life of Brian.
Whether the bandwagon takes off or not, is very much a matter of the moment and who starts it rolling. Its momentum, usually is independent of the merit of the case.
It just strikes me as a completely unnecessary risk, when there is so much material that can be drawn from that have none of the issues. Why take that risk?
