Way back when the Sand ninjas used Genjutsu to put everyone in the Konoha arena to sleep, Kakashi said passingly that Sakura had an affinity for Genjutsu. I really hope that she develops her skills in the storylines to come because I really hate how she's the stupid weak girl that nobody cares about.

I don't think anyone in the anime should be like that. Not to say that everyone should be uber, but everyone should be at least "useful".
