i mean can u even imagine having a 4 tails running loose on Konoha?
Yeap! that would make for great entertainement!

and about those saying that this filler is like the others, well you must have been smoking something pretty good. This arc is actually the best one in shippuuden so far. It's not about the story, which in this case is pretty generic. It's just way better directed than the non-filler arcs.
