Honestly his role is completely pointless.It could have been Kakashi himself destroying the meteorites without Sasuke and the result would have been the same but all he does is sit on his ass and give orders.The only reason Sasuke is shown is to have Sasuke fanboys attend the movie
Correct.
What makes it worse is that Sasuke "chaned" at chapter 699 and was even talking about how Naruto helped him walk on a Path of Light, but they didn't show Sasuke at Naruto's wedding.
I mean I don't want to see the man in a tux, but he could be standing from afar with his arms crossing and a smile. Naruto could of turned around and looked at him for a moment while smiling, before returning to his wife.
I get why his character role was pointless because it is Sasuke in a NaruHina movie, but the fact is there are some scenes where Sasuke SHOULD of been there, and he wasn't. 3 minutes is a freaking disappoint considering half of the Naruto manga is about Sasuke.
