With Sasuke in the movie, it will gross more than The Last. Kishi even falsely advertised Sasuke in The Last's previews, but only showed up for ten seconds at the most, and he still stole the entire show for me.
But a SasuSaku movie entirely. Hell no! Why do I want to see a movie about a couple that represents sexism and abuse with their retarded faps, who also support sexism, abusive, and murder towards women, getting all snuggly? SasuSaku is garbage and sends a bad message to females stating that:
"Now, just because your crush tries to kill you three time and treated you like trash since you were little, it's still alright to cry, fangirl, ride his nutsack, obsess (Because it is not love), and spread your legs for him. And everything is okay, because he said he was sorry and gave you a forehead poke."
