Who knows. But it was popular in Japan and its shown to have that cult popularity in America, despite a very slow Fansub and ADVs horrid launch of it here. I mean, its 2008 and people still talk about the show, not just on 4chan.
But only time will tell. Still, my other point was, people don't have to go around hating shows just because they are popular. And other people don't have to go defending shows just because they are 'niche' and they hate anything with a high rating.
'Narutards suck, fucking Princess Tutu is the best Anime ever!'
Well that doesn't make Princess Tutu good....
