Hmm. Makes sense. What is unsettling about these episodes, regardless of how these episodes are termed "supplemental" or "filler", that they still appeared out of place. The organization, timing, and especially the transition of events within each of these epiosdes seem to be akward and forced, i.e. Kakashi-revealing-his-face episode. Even if one doesn't read the manga (like me ^^) one can still sniff out the difference between the earlier episodes and these "supplemental" ones.
Really? You liked every episode of Naruto? Even the Ino-Sakura's flash-back fight?
Although I agree some of these episodes are better than some of the actual filler's from earlier episodes, it will nontheless, be a joyous occasion when the story reverts back to the normal flow.
