Long running animes

For me there is nothing worst than a long running anime, but there's nothing better. They can be so irritating but they can also be some of the best animes out there. When they're good, they're great but when the same arc has been running for the last thirty episodes you wonder why you're making yourself watch them at all. And I think that if I wasn't such a Narutard or anime freak I would have given up on a lot of them a looong looooong time ago, because lets be honest it just gets painful.
