It's kinda stupid though lol. In the last and in boruto the movie he didn't use that power so its kind of like he was allowing all that chaos to happen especially in the boruto movie. Point is Kishi nerfed him heavy. His rsm looks way better than his bsm anyway so idk why he made him use the downgraded form
I get that part.
It does suspend belief when you know a simple gathering can change it all.
However,that movie started sucking as soon as the "villain" got there.
His appearance was a knock of kidomarou and his abilities never made sense or explained.
Din't even fit in with what we knew about the rinnegan
His friend was stupid with stupid unexplained powers.
Lets forget the last half lol
The only thing i can come up with thuogh is that the fight was naruto's not the tailed beasts fight.
Maybe he didn't want to include them for personal reasons.
They been through enough already as it was.
