I think the manga artist jumping the shark.

That little brat learning a kage level technique?

Pain being able to single handily destroy one of the strongest Ninja Villages?

If Pain by himself is so powerful, why didn't Akatsuki take over the world years ago with brute force? Why are they bothering to capture the tailed-beasts or go through their ridiculously elaborate plan to take over the world?

There seems to be a pretty big plot hole.
