Yeah man that was the most spoilerfull intro for a show ive ever seen. The director of the intro has one up on Kishimoto in my opinion though, He actually uses those minor characters like Neiji, ino and rock Lee and has them fight instead of nameless jonins no one gives a shit about. Hell what is Kishimoto actually had Konan take off her cloak and show them big titties off in a fight with ino, sakura and hinata like the intro. Hell for all we know they might add that kinda filler to the arc.
Damn you're right thats so fucked up, everything was to defeat madara and Naruto acts as if he doesnt exist.
