The plot is very lousy, seriously. Here's a very breif summary...
Tsuade, Jiraya and Orochimaru had a weak childhood friend we didn't know about. This person later becomes and evil villan, a threat to all nations.
When Kakashi was a teenager, this person put a curse on him, a curse he still carries to this day. Kakashi is destined to die! He undertakes a kamakaze mission.
It's up to the Hidden Leaf's youth to save the day.
What's lousy you may ask?
It's unoriginal:
- Like Orochimaru, this character becomes a 'mad scientist', carrying out inhumane experiments in order to get strong
- This villian is 'invincable' and 'immortal', just like most villians who end up getting killed
- Yet another person after the shiringan
- The 'curse mark' has been done before
What else lets the film down?:
- Sakura's typical 'violence toward friends, useless in battle' trait
- Chemeria's are the theme great, time to get creative? NO, all the chemeras seem to look more robotic then organic
- Outright silly stuff occure also, such as Naruto creating a chain bridge of shadow clones, Tsunade knowing how to tamper with the shiringan, Naruto having a mild heal/repair ability
I'll leave you on a high not however, what's good about the movie...
- The fight scenes are great; each team gets some attention
- Naruto's determination to "Bring Kakashi back" is realistic (don't we know)
- We get to see what Gaara can do without the 1 tailed badger
These elements make it worth watching and are the reason I gave it a good score.;)
