Most series get worse the longer they go. However, One Piece been going on for 20 years and is getting better and better. Dragon Ball, although it doesn't have the best story and execution in the world, is getting better and better as time goes (not better than OP though). Bleach, Naruto, etc. got worse because of studio intervention and the author didn't know what do do with the story.
