She's supposed to be one the simplest definitions of a moe character. The idea is that her personality generates a feeling of wanting to protect her. I find her helpless to the point of being annoying. That's why the definition of moe has gotten so complicated, not every personality type appeals to everyone the same way.
I do like the way they're progressing the story better than Kanon so far. We all kind of know that Tomoya is going to end up, or at least be closest to, Furukawa at the end of the series. Kanon did everything in separate arcs, where most of the characters barely were even involved with one another. Mai and Sayuri didn't know or talk to anyone else, Shiori's only connection was being the sister of Nayuki's best friend, etc. Yuuichi ignored every other girl while the arc focused on one of them. It's a little more like the way AIR was told.
It's still the introduction, but here, Tomoya is still going abound his normal business, gets attacked by Kyou every day, is witness to the fights with Tomoyo daily, and meets other girls around the school. Yet, each episode, the progress the story with Furukawa just a little bit. If they keep it up even when the major character arcs begin, I think it will come off a lot more realistic.
Realistic, even despite the Hit Counter.
I loved the part where he told his entire class that Kyou was Bi.
