My opinion of this game:
1. Start with Dragonball Advanced Adventure
2. Replace the characters with Naruto characters
3. Remove everything that made DBAA fun.
Voila! You have Naruto Ninja Council!
Anyway, some info on the game:
Story mode doesn't really follow the manga stories. You basically play through several platforming stages one at a time, killing other ninja (trainers? rival village ninja? i dunno) collecting leaf village icons (to unlock pictures...."yay?"), and collecting throwing weapons and elemental jutsu scrolls (fire, water, wind, earth, lightning). The game only allows you to keep one throwing weapon at a time, same with elemental jutsus. Elemental jutsus are used to fight your enemies and clear obstacles in the stages.
Each character also has 6 unique jutsus plus 2 more that can be unlocked by finding a hidden scroll. For example, Naruto has his shadow clone and sexy jutsus, while Sasuke has his fireball justu.
At the end of each stage, you'll fight a ninja boss that also has their own unique jutsus and life bar, all of which are taken from series, but not given any background information or backstory. However, Kakashi will give you a small bit of info before each battle to help you out.
Free mode bascally lets you go back and play previous stages. Visual mode is where your unlocked pictures appear.
Overall, being a slight fan of the anime, I found the first round of the game entertaining (played story mode once with Naruto, then tried to play again with Sasuke and got bored quickly), but I won't be playing it again anytime soon.
The unlockables (recycled story modes, images gallery, and sound test) just aren't enough to give it any appealing replay value.
LOLSPOILER
The unlockable character is Kakashi
