When I first heard of Harry Potter back when I was around 9, I was indifferent to the series. I don't think it's a shitty series, as it is a lot better than a series about sparkling "vampires" and Miss "I'm So Perfect I'm Such A Spoiled Crybaby" created by the Justin Bieber of literature herself, Stephanie Meyer. But when I was growing up, kids around my age were really crazy about Harry Potter, carrying those books with them. I mean, I just don't get it. But hey, It's their choice, I guess.
But yeah, a lot of the fandom and hatedom can be VERY cuckoo for Cocoa Puffs. I totally agree, Mayu!
