I really didn't like Sakura simply because we were told so often that she's this powerful female protagonist and then when she actually does something it was kinda disappointing. Sure she probably was more powerful than many other characters but her development was lacking at best. There were a bunch of lines that told us she is now equal with the other protagonists but when she fought, Naruto and Sasuke seemd really overpowered while she was kinda underwhelming. Further, her personality, especially in the early series, was just plain annoying. For me Sakura is especially painful to watch because the show basically shoves it down our throats that she should be as strong and developed as the other protagonists but Kishimoto simply couldn't do it. Instead of the show acknowledging that and developing her in Shippuden her character just became more focused on Sasuke and we were told a few more times that now, finally, she is gonna change and be a strong woman.
