It would have to be Bleach and Naruto.
Bleach started out amazing and then it just seemed to lose its way. I went into the arc where they rescue Rukia and by the end I question why no body died. These people were trying to cut each other down and there wasnt a single fatality. After that they went into all these other story lines that had nothing to do with finding Aizen and when they did go after him the story just dragged its feet.
Naruto has a similar problem with pacing. It takes forever to get anything done in that universe. Its "are they still on Nameak" all over again. And by Shippuden all the side characters get put into the background, which was in really stark contrast to the Sasuke retrival arc.
