Ughh, that's just not good, they shouldn't be jumping on things when they didn't happen in the manga. As I said before, Perriot is going to run the 615 moment into the ground, what significance it has, they are just going to make it some extremely overdone moment.
Perriot is going to run Hinata's other moment into the ground again, they had to make an entire episode over her getting steamrolled by pain, this is the issue many others have with Hinata, her role is minimal in the manga and yet they try to display it being more important in these extended scenes from the anime. Filler-canon is what people call this stuff, the scenes are centric to a canon event but they are extended for something else. Anyways with this simple hand holding moment or speech, they are going to blow things out of proportion again, extending this scene to be another 20 minutes when it was only about 15 seconds in realtime. They are going to cram it with more flashbacks and memories, stuff even like Naruto totally noticing Hinata yet it would not matter by the manga much later. One entire episode is not enough though, they may cram this into an opening or closing sequence. Its not Hinata we hate, its how the fanbase and even anime developers can overblow her proportions at times, and doing this with another episode on a moment which was not even a chapter just downplays her character even more, this is why many have a hard time adjusting to her character, she is too simplistic, developed in the fillers and anime more, and just seemingly milked anychance the anime team can get. We never see this problem with other popular characters like Sakura, Shikamaru, Gaara, Neji, Lee, Tsunade, or Anko. Naruto gets the attention he needs as a main character and Kishi just uses Sasuke a lot but he is his favorite character and doing that for manga reasons is still acceptable. Hinata is the one who gets over inflated to much.
We don't see any other big moments for other characters drag on, they happen as they should. Only filler-canon I can think of for Sakura is when she had a larger role in trying to help Naruto train for his wind style, mainly by giving food pills or reprimanding Sai for criticizing Naruto only to find out Sai tricked her. Everyone else has their moments and lets them proceed as they naturally should. Only Hinata gets special treatment. Why not give some fillers to others like Shino? Many people love Shino yet he is always stuffed in the back. All this expansion on Hinata does not help her case as a character and people praise her like it happened when it did not. If all this stuff happened with Hinata, then by right we have the right to do the same with Sakura which is much bigger still. When that episode with 615 comes, any memories or whatever else they may show Naruto having with Hinata or noticing her, it should make no difference by the time another manga event occurs. Hopefully more NaruSaku stuff would come up by the time this episode occurs and debunks the stuff, well its still bound to be nothing of merit being filler canon if they extend this simple scene much more again.
There are two different types of Hinata. Anime and Manga.
