Ridiculous, all of it. I don't deny that evil can be attractive to us, but if you use that as a yardstick on everything in the world, you're bound to see evil where none abides.
This is children's literature. As an avid reader myself, I am pleased to see something out there that gets the video game controllers replaced in children's hands with a series of good books. IMHO, I see nothing evil or subversive about them...I think they're simply a good yarn that kids and adults alike enjoy. This is just so much hysteria. There are other things to worry about when it comes to being a corrupting influence on our kids. The Harry Potter series isn't one of them.
Anyon who takes the trouble to read harry Potter knows that he is undergoing an apprentiship. Yes, he defies authority, misbehaves like a typical kid, ignores the advice of adults he should trust -- and in each instance this leads to trouble.
Most recently, his disrespect for authority resulted in the death of his Godfather, the very person he was trying to save. Hasn't anyone noticed this?
The movies can't show this as well as the books, but there is a rather effective scene in the second movie, in which Harry denies having anything important to say to Dumbledore. Minutes later (movie time) he hears Voldemorte (Riddle) do the same thing.
The point is to show a normal kid doing normal things, and hopefully learning from the consequenses, not to show a flawless superhero.
