If they want to add scenes in fine. If they want to add in filler to keep the pacing of the scene fine. If they want to push a scene back like they did with the sage training fine.
but they dont get to cherry pick the scenes to their liking. when they start doing that they start going down the path fo the Full metal Alchemist Anime. the one that no longer even remotely resembles its manga counterpart.
Sorry Derrock but your wrong here. because if they can change something as clear as a SasuKarin moment because they feel like it. then they can change somthing more signifigant like the NaruSaku huug or the confession becuase they feel that Hinata would be better in that moment or mroe realistic.
But the writers had done this since when they first started animated the series, Catsi. And there will be more soon, though its very unpredicable. We are not sure where and when are these alterations can occur. While the graphic violent/disturbing/inappropriate scenes are the ones we know and are expected, but alterations such as a dramatic or intimate scene, it can go either or (as in stay as its manga counterpart or to be extend/change for the pacing).
The animators had done this to NaruSaku when following the canon back in Part 1, especially their "date" scene before Sasuke left the village. That scene, which was explained in the Debate thread by yours truly, had so much alterations, I don't know what was going on with the writers' mind. Hell there was more stuff before that scene that were alter for no purpose whatsoever. (Primary examples were Sakura and Sasuke's intros, adding the rest of the Rookie 9 on Episode 1 when they were supposed to be first in the Chunin Exams and many more... leafninja.com has the list of the alterations though its incomplete.) Even Shippuden first started with Episode 1, the NaruSaku reunion was altered (good, but left out Kakashi and Tsunade until later on and added on Moegi and Udon for whatever reason, oh they were added in for a filler of a D-rank mission they had completed).
But they do cherry pick, not constantly but hidden here and there. The writers over at Pierrot doesn't always follow the straight line Kishimoto had gave us in the manga. They will alter a dramatic/intimate scene in an instant. But however, Hinata won't go that far on hugging Naruto after the Pain fight. If that occurs, it will not only ruin the upcoming moments for the "crazy confession drama" we're going to see once they reach the point but also make to see that Hinata is very important to the storyline when she is not.
