I actually like her ... she isn't that bad , if she wasn't so addicted to sasuke. Her Character is more realistic, the ordinary , human girl among all these beasts & semigods. Kishi just carelessly throw her character developement away. People are constantly judgying her , because she hasn't archieved much yet , but they always forget , that she isn't like kakashi & co , if you compare her with the other Konoha ninjas , you will get another picture of her. She was never meant to be a beast in terms of strenth , like sasuke or naruto. She is more the core , the connection to the normal people . Or basically the anchor to Humanity. So everyone chill out
