One would hope that Naruto Shippuden canon episodes would be good (at the very least) when you consider the sheer number of fillers they pump out.
One Piece has a problem. I mean is it not embarrassing when it takes 3/4 minutes to cover 1/2 panels?
Before they used to have a good number of fillers between arcs, and you know what? I really enjoyed those. Meeting new characters, lots of good comedy and most importantly seeing the crew interact with each other in peaceful situations.
They should put in some fillers so that episodes provide some good story progression.
