I consider that movie nothing more than a filler. It basically just fills up the time skip in the manga with a boring villain and a cliche love story.
All I'm really interested is whether the movie ends with Naruto beating the villain with some kind of special Rasengan. All the ones I watched ended that way. I can't remember if the one with Naruto's dad and the tower ended like that, because it's so forgettable, but the one before had it. You know, the one with the guy with multiple stolen Kekkei Genkai and Shino's bugs digging a hole as big as a house by eating dirt.
! He uses a bunch of his newer rasengan techniques in this film (rasenrengan and wakusei rasengan), but the final blow might've been either a normal rasengan or a wakusei one. I'm not sure, the movie was kind of boring so I've forgotten, lol.
