That was truly horrible. I'll give it 2/5.
cons
- Obito: If you want to be taken seriously, stop whining. (You were doing good for chapters, but now you've ruined it!) Stop talking about Rin. Also, how dare you say the Fourth was weak for not protecting his wife. First, you killed her. Second, at least the Fourth was able to overcome his grief for you and Rin without betraying every single moral he ever stood for. Don't you dare criticize the Fourth.
- Madara: You have a trump card it, use it! Stop getting ready to attack your boyfriend and do something villainous. If you don't take this war seriously, no one will take you as a villain seriously.
- Pacing: I feel like I just read a half chapter. For example, why was it necessary for Naruto to say it was awesome to learn Sage jutsu? It's not like that furthered the plot. Also, was that pep talk to the Fourth (doesn't need a pep talk) necessary?
- Sasuke: you're my favorite character but you're testing my patience. Do something!
- Yin Kurama: Yang Kurama says it'll be difficult to convince him. Then Yin gives Naruto chakra. Even if Yang hadn't said that, this is bad because poor character development of Yin and fastest, most unbelievable talk no jutsu ever. You are Yin. You are dark. Why are you giving the Fourth a pep talk!?
- what a coincidence: So Obito why did you attack the Leaf that day? Was it because Kushina's seal was weak due to giving birth. Thus, allowing you to free the Nine-Tails to attack the Leaf? Or was it because Rin? Choose one or the other. Were you happy when both fell on the same day making it the perfect day to attack?
pros
Obito did something other than standing there and shrugging off blasts.
His weakness explained: He isn't just weak to Sage Jutsu. He is weak to natural energy which is a component of Sage Jutsu.
best thing: excellent development of Sasuke: He is not jealous of Naruto anymore.
speculation
Perhaps Kirin will be effective, but with that box I'm doubtful. Sasuke has to create a rising mass of air in order to create a real thunderstorm (natural energy). I wonder if the box goes high enough to allow for that. Regardless I suppose Sasuke could just defend Naruto will he attacks if Kirin is out of the question.
