"All the fillers are sneak peaks at the Infinite Tsukuyomi World" - that is what the Naruto Anime producers should say at the end of the whole anime series. Some of them have been beyond crap, defied very basic laws of jutsu, contradicted canon/legitimate manga events or rules, and have been inconsistent. I reckon if the anime producers say that those fillers were events that happened in the Infinite Tsukuyomi World, those parts of the anime would be redeemed and seem whole... oh, and consistent!
