I've finally watched it today.
And I liked it. Actually this was the first Naruto movie I liked so far. There were surely some flows, but generally the idea and the interpretation have somehow touched my current state of mind and soul.
I only wonder, why in the world of Naruto's dreams and wishes Jiraiya was also dead?..
Speaking of which - RTN version of Jiraiya's death - small doujinshi by ~Lantern6 - [link] (scroll till the very end) ^^
