I've watched a few of the Potters and read one of them. I do think they are of a different quality than other fantasies.
There seems to be a dark side/light side portrayed in some of the fantasies that I tend to have no problem with.
But some of the others seem to have the dark side/the good side of the dark side/and the light side. I'm uncomfortable with the "good guys" on the dark side.
But there aren't any "good guys" who are "on" the dark side.
You have some "appearances" of evil. And you have characters that struggle against the evil.
