I don't watch Naruto, but this movie had such bad premise it was unbelievable.
Generic evil guys: We need to bring back our god so we can conquer the world with our zombie robot army, but there's only one person who can stop us.
Princess: I'm a douchebag
Naruto: HURR DURR HURR RASENGAN
*evil thing asplodes*
Princess: Marry me Naruto!
