Exactly. I think he once said that this movie is throwing everything he has in mind in terms of fanservices, his intentions, and of course, the story of parental love. Again, he could have only Naruto going to genjutsu and Sakura could have been AU! Sakura. Simple as that. But no, he decided to go with them to expose many things, hence the fans' misinterpretation. Also, Naruto's love for Sakura is exposed in this movie in couple of times, so I guess this is Kishi's way of letting us remember that Naruto is Naruto. Again, the date request at the end wasn't needed at all, but Kishi did it to give us an idea that NaruSaku can happen, but we have to read the manga to find out. Basically, it's like an advertisement to newcomers and I applaud to that. I really can't wait for this movie.
Exactly - I think that's what hits me too. Kishi did not have to make Sakura come along for the ride with Naruto - he could have had Naruto go through the experience alone. But instead, he did bring Sakura along into this genjutsu, and he gave her a crucial role in the movie - she was the reason Naruto decided that he needed to go back to reality. Its possible that he would ave eventually came to the same conclusion that this Minato and Kushina were not his parents, but who knows how long that would have taken or if it would not have happened at all.
Also, it shows how important Sakura is to Naruto as well, and vice versa. Naruto chose Sakura over the fantasy of being with his parents, a fantasy that gave him "everything he wanted". Sakura chose Naruto's happiness over her own.
It's just an incredibly excellent showcase of Naruto and Sakura's bond, and I still can't get over the fact that Kishi focused on it as much as he did for the one movie that he has a major hand in. It just goes to show that Kishi does consider this a relationship that it important to him, arguably in the realm of importance as Sasuke and Naruto's relationship (given that that relationship for once took a back seat to Naruto and Sakura's completely).
