Naruto Shippuden, le film : La Flamme de la volonté

Usually a movie made from a series mean bigger story and bigger everything. In the Naruto franchise I haven't seen one example of this fact. On the contrary it is quite the opposite of the epic anime. It is obvious that the writers are out of ideas. To be honest every Naruto movie including this one has this one message repeated ad nauseam. And the message is always the same,friendship. There is no need to make 6 movies to tell me this. At first this movie started great with promise of epic proportions. Sadly there aren't any. I understand that the writers want to save their best for the anime. But couldn't they just for once show something that actually would be interesting. Like the period between Naruto and Naruto Shippuuden. We are talking about two and half years. Surely something interesting happened in that time. Or why not a little background story of one of the multiple characters like Lee or Kakashi. He is supposed to be this super ninja but always gets hurt. So why not show us how he earned this reputation. For me these movies are redundant and they should stop making them. Of course this won't happen since Naruto is big business. As I understand the fourth Shipuuden movie has already been released and there are plans to make fifth movie. Well,I can only hope for some improvement.
