Mega Spoiler!

I like Kakashi and Shizune. But honestly...

Bringing them and everyone else who died "today" back in the end?

It's a total slap to the face. It's the same crap out as "simulation," "dream," or "alternate reality/timeline." It's like pushing the reset button if you dont like how your games going.

It bugs me.

Makes Hinata living seem... pointless? I mean, if she DID die from Pein, she'd be back now? So the fact that she DIDN'T die... suggest to me, that this was a last minute thing. I think Kishimoto was feeling bad about either Kakashi or Shizune dying, and wanted to pull something out of his ass for Pein's big finale.

I mean it makes NO sense for Hinata to survive if they were all coming back in the end. It would have been so much more epic emotional strife if she died.

Oh well.
