Quite a lot of the filler is terrible, Moms Alliance anyone?

But c'mon, Kakashi and Gai filler has been awesome! We get to see fights that the manga skipped, the manga isn't perfect either.

Animation quality sometimes sucks because not enough people watch it to get them enough money to make it good, instead everyone stops watching and complains about necessary filler.
If you'd all just watch it, it would get better.

But no, complain.

I'd like to see anyone who moans about it make better episodes every week, organise everything, get the money to do so and have people actually enjoy it.
