You guys seriously hate Sakura...she is a civilian so her Chakra us abysmal..so thats why she is useless at the beginning, but after she learns under tsunade, she teaches her the Chakra accumulation which goes well with Sakura since her energy manipulation is league's above everyone but she is useless with so small Chakra so after she can use more Chakra she becomes amazing. Her strength didn't just fall from the sky you know..in terms of getting stronger step by step and some one to respect for her effort is sakura.Sakura.. most don't like her because she becomes stupid when it comes to Sasuke..
calling Sakura a talented... prankster. everyone knows that in the beginning, she was just a minor character in Naruto and Sasuke's story (to take the last place in a team of three). then the author made her stronger, because she was laughed at a lot ... somewhere there was an interview where the author talked about this. She has a huge power that comes out of nowhere (I don't believe in such a talent...she can't be better than a tsunade).
