It's not just that but it's the SECOND time she has tried to die infront of/for Naruto. It's disturbing.
It's more defensible than the first time, though. If Kishimoto hadn't written in the first time, we would have gotten a NS ending, probably. That kitten fed nH fans so hard that he ultimately ended up changing the story to serve them, even though it also resolved Hinata's feelings via her smile.
There is a very good chance that Naruto would have been fine regardless vs Pain. Vs Juubi, I can at least see the argument that she was providing a service that could not be substituted, given that there was some garbage about how Rotation wouldn't work.
