Re: manga to anime and scheduling.!!
I prefer filler than go on Hiatus only if it has done right. Fillers that are relavent to the main plot makes it better plus you get the connection to the storyline.
Good Naruto Fillers such as:
Twelve Ninja Guardian
3 tails arc
6 tails Arc
Some Good War Fillers such as 7 swordsmen, team 8 investigation, deidra escapes, sound 4 and Hayate
Bad fillers are random or stupid flashback that doesn't make up the story like for example after pain arc, or Sea of the Adventure.
But Holy shit, the last recent episodes are ****in Terrible, if the Studio continuing making worthless fillers such as The Retarded Kid that Looks Like Kakuza, THEY NEED TO GO ON HIATUS ASAP!!!
