In comparison to the other movies, how much pairing fanservice do you think this movie had?
In my opinion this one just skyrocketed. I herd people say that naruto shippuden movie 3 had NS fanservice but I didn't really see any bit of romance in it. In fact, the only movie that I noticed legit pairing fanservice was either with Naruto and random princess or that one movie where Naruto was holding Sakura and her immediate reaction to this was to slap him (more like punch him lol). Even then it was for strictly comedic purposes. With RTN though, we get way more pairing fanservice thatn we've ever seen in any Naruto movie so far. This really confuses me how others will simply brush it off as "just a movie" when it's the only movie that Kishi has openly admitted to having 100% control over it (or so I've herd). I wonder if we'll get another pro NaruSaku OVA.
About movie 3, it's not that it is romantic, rather words were display to describe the relationship that are more than friends. For example, Sakura was mad at Naruto and Sai for leaving the hospital though when she hides her face from Naruto, she smiles gently as she knows Naruto recovers fast. Not sure if it's just translation style, but it's kind of cute when she said, "That's my Naruto." Then Sai grabs the book that says a person who shows anger to a man is an act for she loves the guy. Sadly, both of them are dense to notice the connection. There are more tidbits but my favorite one is the last one whereas Naruto made a speech and everyone in Team Kakashi were encouraged by it. Kakashi decided to team-up with Naruto. Sakura got hyped and then Sai was like, "Oh yeah! I remember reading about this. A woman gets infinitely strong for theman she loves." For this movie, that seems to be true.

Also, that prison break was nice and funny.
Now for this movie, boy, Kishi went deep to tells us that there's more than just friends in NaruSaku. You had many 3rd party that thinks they're dating, they save each other, sacrifice their happiness for one another, and the list goes on. Need I to remind the obvious parallel that a lot of people noticed. It's clear as day. I came to see this for enjoyment, but now, I'm going to get a whole lot of excitement.
