Sakura had to be directly controlled by someone else and was only useful to make huge punches. In the Pain arc she punched out one summon animal which was indeed useful but then was immediately sent away from the fight to heal people.
In current arc she tried to Leeroy Jenkins into a GOD twice, the first time almost killed her and the second time was stopped by kakashi calling her stupid. Now she's only good as a chakra battery and she STILL ran out of power just before sasuke could run to the portal.
Infact, since Sakura running out forced Sasuke to teleport in, you could say she's responsible for Obito's death because it means Sasuke didn't have the teleport ready for this chapter.
is it just a remake of the 2006 anime or a new story? if its the first then sis bye it was one of the most boring anime i have ever seen...
It's the same concept but will have a new/original route, which means the main plot and characters will be the same but the progression/events will be different.
