Nothing could be worse than over one year's worth of episodes consisting of nonsense during the period in the storyline when Naruto is supposed to be training. The individual arcs will be forgettable, but this stretch of fillers of unprecedented length will be remembered in the years to come...and that's assuming they don't pull a Kenshin.

The situations in both the Naruto and Bleach storylines are very similar. Both fillers take place during a period where nothing really happens. The characters are just preparing for the upcoming stuff (Sasuke / Aizen). The Bleach filler arc has been successful because it is actually semi-relevant to the plot. Ichigo gets to work on his bankai during the fight against the Bounto and later on it won't have such a huge impact on the overall storyline.

However in Naruto's case, none of the small filler arcs have anything to do with the story and they all have zero effect on the overall plot. They're just "random" events that happen. What if they do a big filler arc like Bleach but it's bad? Well, that shouldn't happen if they put some effort into it to actually make it good. I mean, if the Bleach one works then Naruto should work too because they're both in identical situations.

And I do realize it's too late now to start a big filler arc. I'm just saying they should have done it in the beginning. All this Naruto-hate is the result of what's not working right now, and that's the small filler arcs they've been mass producing.
