UChessmaster that is not exactly the case here.

Kakashi's "death" allowed him to forgive his father and let him let go of one of the greatest pains in his past it allowed him to grow while resolving the plot point of his father.

Shizune didn't even really get much of a death scene they just ripped out her soul and moved on. Honestly nothing was lost or gained with her.

Hinata never died in the first place so she wasn't resurrected at all. I do think she deserved the hug more then Sakura but with her injuries and the fact that Naruto's interest lies in Sakura its pretty sensible that it wasn't her who embraced him.

So really what was lost here? A bunch of nameless villagers didn't end up dead and we got a epic battle that greatly improved Naruto and took care of Pain and Konan (plus the rain village for now). I really can't see what the true hatred for this plot twist is.

Jiraiya is still dead. Its pretty clear those injured were not magically healed in any way unless they were killed meaning Tsunade is still unaccounted for.

Overall I really liked this episode it felt like a proper conclusion to a epic arc. I'm a bit sad we are getting some filler now but hopefully its a quick bit before they get back on track and continue the story.
