Well from what I have seen many people are disappointed by this chapter expecting either something more dramatic happening, not liking that Naruto had a breakdown like this and also thinking a bit of a cliche the way Hinata stepped up to be his mental handicap.
While I totally see your point of view I also disagree with that in a big degree.
Naruto hasn't stopped going forward since he joined the battlefield and it is only logical that all this would really be too much for ANY 15-16 years old kid to handle, while being in an emotional stable place. Don't forget that Naruto had always stepped up to take a hit and save others and this time he couldn't do anything to save thousands of them, while Obito is really rubbing this to his face. I also saw that some people are comparing this to the Konoha incident. Don't forget that Naruto didn't show up until after
the mayhem had been done and he couldn't do anything to save those people in the first place (not to mention that after all they were saved by Nagato).
So to sum this part up I believe that this was really a necessary part for Naruto to go on into finally saving the whole ninja world. Also imo internal changes can sometimes be more of a cliffhanger than something really dramatic happening or a sudden huge power-up. I will agree that Kishimoto could have presented to us that change of determination in Naruto in a better way, but to be honest that one doesn't disappoint me either
To wrap it up as far as Hinata comes, maybe it had to take something really bad (like Neji dying and Naruto hearing his final words) to make him deeply realize what Hinata is and have always been for him. The way we see him really squeezing her hand near the end, I believe it is a biggest reaction out of Naruto than a thousand words could say. And just saying I was never a huge NarutoXHinata fan. :P
