Do you fall asleep whenever you watch Naruto? because the movie was clearly better than the last ~30 episodes... or even better than like 90% of the whole series.
There was absolutely no reason to fall asleep because it was boring... None at all not even the story was "boring" it was the most common story ever.. nearly 50%of the movies, may it be life-action/animated/*insert random movies here* have the same kind of story.
you are just overreacting because it wasn't "super special awesome!"
neither the animation was bad nor were the fights..
It wasn't a very good movie either... it was a regular 08/15 movie. (edit: ehh... is the phrase "08/15" actually used outside of germany? well if not, it simply means that its nothing special and that we've seen something like that many times before just slightly different, but it doens't mean that its bad because of that)
btw you should never go into the cinema or watch a movie excepting something really *AWESOME*
many people actually did the same with the movie "300".. and expected a super-great story behind everything... but I who knew a bit about the comic etc. was excepting really great animation and especially slaughter, because slaughter was nearly everything the comic had.
The same goes with a Naruto movie... all there is in a Naruto movie are some good fights. Too bad they don't focus on it more.
