Awwwww shit son! They just summoned Shenron up in this bitch!
Naruto believes in the you who believes in me!
I think it's kinda cool this didn't end in another battle.
I personally don't have a big problem with Ressurection techniques as long as they kill off the user. That way, death isn't "free" it's just shifting the cost around. As long as doing this kills Nagato, it's fine. Although from the way Konan spoke, he actually could do this and be fine if he hadn't used up most of his chakra already.
Also, if each of those lights is a person being brought back, a lot more people died than they made it seem. I was under the impression that Tsunade had managed to save just about everyone in the village so far.
It does seem weird though if Kishimoto knew he was gonna res people who he didn't just kill off Hinata when he made it seem like he was killing her off...maybe he didn't want to tip his hand. People could believe the older characters dying off, but perhaps if one of the kids dies, people start thinking it isn't going to stick.
