If there is one thing you can change about the series, what would it be ?

[sravan]

reanimation of jiraya so that he joins the battle

 

[SSU]

The downfall of Madara. There should have been another way to end his reign without completely humiliating him.

 

[NineSNS]

Hard to say - it's not done yet.

 

[cafe123]

Revival of Kaguya, wish it didn't happen.

 

[Cresee]

Hiruzen not existing.

 

[Sugiyama]

Anything regarding the Otsutsuki family would need to go. I swear since that family showed up, everything got so confusing.

Agreed, they should have remained as legendary myth nothing more. This and the whole reincarnation stuff shouldn't have been introduced in Naruto, IMO.

Hiruzen not existing.

Or simply Hiruzen not being such a complete feeble leader who lets someone else pull the strings in his stead.

 

[NotAFanBoy]

kaguya not being introduced would be a good start I think....

 

[awesomeseimei]

I'd add Danzo dictatorship arc.

 

[coucou myriam]

The way how Kaguya was sealed
The way how Madara has died
Obito still alive and return to Konoha with Rin
Rin still alive and was stuck somewhere but Obito knows nothing (excuse me for my strange imagination but I really liked the love obito holding for Rin)

 

[Natsu Shazneel]

I would change the name of the show to Hokage. That way people have a excuse to call a Hokage the main character since it's named after the show.

 

[Joseph Gomes]

Remove everything about Kaguya from the timeline, her entire existence is unnecessary
