It was a rather dull chapter. I expected more. 3/5.
I think people hate Sakura not because of her proving to be an absolute annoyance, but because in comparison to her teammates, she is nothing. The fact that it took 3 years of gathering and storing up chakra to be able to use a Jutsu of this magnitude, which, again, is really nothing compared to what Sasuke and Naruto can do, proves that she's still not quite on their level. I have no love for Sakura. I dislike her character, but I'm still being reasonable. Sakura needs to do more if she is to compete with Sasuke and Naruto to the slightest.
I'm not convinced that she has surpassed her mentor.
Anyways, just my personal opinion. Not forcing it on anybody. Everyone is entitled to their own opinions.
