I don't understand the current obesssions many people have for pirates or Harry Potter. I liked pirates when I was 4, liked them a lot, but at 22 I don't feel the need to decorate every item of clothing I own with a skull (or a bunch of skulls). The worst kind of crazes are those that followers believe to be quirky but are in fact far too mainstream and uninspired to be anything but a trend followed by sheep, and the pirate obsession is a perfect example of this.
As for Harry Potter, I couldn't get through even a chapter of one book without wondering what the point was, and the movies are just as irrelevant, packed with cliches. Maybe I'm missing something, but I've sampled both ideas and found them boring - perhaps other people feel the same but are afraid to admit it because they want to join in?
