The Ten-tail's attack on the last page was awesome, both for its power and the foreshadowing it gave me. I've got fair reason to believe that not many shinobi are gonna survive that attack, including some of the major characters, in which case, it would strongly support my theory that Obito's gonna use the Outer Path technique to revive them, just like Nagato did. For that alone, I went ahead and gave it a 5. The only big disappointment I got from it was Obito and Kakashi's departure from the battlefield, the reason for which should go without saying. Now, Minato probably won't end up seeing them.
