3/5.
Nice idea and it wasn't afraid to deviate from the usual Naruto movie format (which is why it got the extra point, all Naruto movies IMO get 2/5) Menma was cool, if underused. Nice to see the Akatsuki fighting on Konoha's side, Sasuke back in the village and Naruto having some character development.
Minato and Kushina were just so dull though, Hinata & Sasuke seemed like they were going to be more present, some of the backwards personalities are a bit too predictable (Shino now hates bugs instead of loving them seriously? just make him like a fun, life of the party character!) Also some character's personalities just didn't change at all... (Akatsuki&Lee come to mind) and there are SO many inconsistencies, like Minato and Kakashi looking the same age, Sai being a happy random guy (even though Sasuke was still around) and the whole idea of Menma was just all very eh.
I shouldn't have been as excited as I was for this movie, having Sakura as a main character was a big mistake and it was all just a bit of fun movie that could've had...a little more fun?
