Obviously you still like them since they're still on the air, but do you think the length of 600 or 700 episode series like One Piece, Naruto, and Case Closed is a pro or con? Is so much content more of a good thing or an overall detriment?
It might be a con in the US, I can't really say. Overall, any show that's had that many episodes is just a show that's deeply ingrained in its fans' consciousness. And a huge success.
