Yeah, i don`t think you got my point... at all.
Kakashi`s dad scene was nice and all, but at the end it needed no resolution, his tale was a tragic one, i would`ve rather they kept it that way, and that`s not even what i meant!, what i mean is that Pain didn`t really killed him, Kakashi died because he used MS twice when he was short on mana, Pain`s technique shouldn`t affect him.
As for Shizune, the fact that she had a quick dead was a good thing, i always perceived it as a way for Kishimoto to indirectly tell us "Yeah, that`s right, Pain is here and shit just got real, and none of your beloved secondary characters are safe", but no, he just had to come and res everyone.
As for Hinata, you misunderstood me again, let`s put it this way, If Hinata survives, she survives, if she instead died, she survives anyway, so why should we care about her well being if she`s going to survive no matter what!?
Maybe i`m wrong, but i was under the impression this arc was about the cruelty of war, and being a ninja is not all about bringing your butt body back, unicorns, rainbows, and unicorns that shit rainbows, is hard to be on the edge of the seat thinking everything is at stake when at the end, nothing is. It`s like watching a movie only to realize it was all a dream, bleh.
Now, let`s say 6 of the Konoha twelve are fighting some foreign ninjas, one of them uses a technique that will undoubtelly kill him in the end, another one gets a fatal wound in his chest/shoulder/whatever, both mortally wonded, yet both survive somehow, you`d be dissapointed yes?
