I have long known that Sakura was a completely worthless Shinobi... it's about time that they finally addressed it. It was nice that it was her coming to terms with her own lack of abilities, though. I mean, she has excellent chakra control, but she doesn't use it for anything. Seeing as how Inner Sakura doesn't really surface anymore, she really has nothing, and I always wondered why she was on Squad 7.
It's nice to finally hear someone in the show voice how worthless she is as a shinobi. Sure, she may be a key character to Naruto and Sasuke's characters, because they try to impress her and protect her and everything, but she really has no jutsu of her own. Sasuke has his Sharingan and Chidori, as well as the Cursed Mark... Naruto has Shadow Clones, Rasengan and the Nine-Tailed Fox... And then, you have Sakura... as far as I recall, the only thing I've seen her actually DO is break a genjutsu when the Sand/Sound Villages attacked the Leaf Village.
As far as the episode is concerned, it's pretty much the same old Naruto episode... Naruto calls Jiraiya "Pervy Sage," Jiraiya protests, then takes Naruto's money to go scam on chicks. Nothing really new or impressive, story-wise.
