Sakura hiden is such a good story, there’re some things I don’t like, but in general is a good story, that shows Sakura more mature and fighting like the great kunoichi that she became, her fight against Kido is completely awesome and shows how she evolved. Besides, her relashionship with Sasuke is explored in a subtle way
Studio Pierrot ignored this story and continued to show their own Sakura’s version, that’s why I hate this studio, Sakura hiden was meant to be a great canon arc in the anime that would show how Sakura is awesome. But they prefer to do fillers that mess up her reputation.
