I shall begin with a defence of the Harry Potter series. Ok, it's not Dostoevsky, but then Ms. Rowling never pretended that it was; it's a series of compelling books for children.
I openly enjoy reading children's books (a chapter of Winnie the Pooh on a relaxing Sunday afternoon is very pleasant) and I grew up with the whole story, which due to Rowling's laziness reached it's climax when I was an adult.
'It's a children's book' doesn't excuse all it's faults however. Some of the dialogue is awful, and a few of the plot devices are maddening, and certainly there's a lot of other good fantasy books for children out there.
Overall though, I think the stories are enjoyable and the characterisation strong (albeit not complicated). I feel the occasional Harry Potter book can be a small part of a balanced literary diet, like having McDonald's once a month.
Now I've got discussion about the quality of the books out of the way, it is time to look at certain things that, I feel have gone a little bit under the radar, and are, as the title of this piece suggests, Just Wrong:
1) Apparently Hagrid's father was a human, and his mother was a giant. Admittedly this is less disturbing than the reverse breeding scenario, but it still seems like quite an undertaking, and one that most likely features in the world of Hentai. Perhaps he used apparatus similar to Catherine the Great's.
2) The centaur Firenze features throughout the books, and begins teaching at Hogwarts in the 5th instalment. This is innocent enough, but the fact that several of the female students have a crush on Firenze is thrown into the narrative without much thought to the bestial implications. Whether this fetish is down to his good looks or his presumably horse like endowment is never made clear.
3) The love potion features a quite bit in the Harry Potter series, not least as an important (though not entirely satisfying) plot device. The concoction makes the drinker infatuated with the 'giver' of the potion. Cue some comically unlikely infatuations, but when the implications are thought through, it is clear that Amourtentia is essentially a rape potion, a magical version of rohypnol.
So there you have it. Give it these 3 disturbing aspects some thought the next time you listen to Stephen Fry's lovely voice reading the Harry Potter stories.
