Harry/Ginny always felt more forced to me than Hermione/Ron did. I didn't see them as incompatible, just that the run up to it felt way too sudden.

This is my exact problem with Harry/Ginny. Harry/Ginny was always the one that felt like it was happening because that's how JKR planned it from the start, and that's it.

At least with Ron and Hermione we got to see them interact and their relationship grow from book one steadily on. Which is why I really have no problem with them as a couple, even though I don't really ship them.

But, when she isn't being used in the background to fill out the world, Ginny pretty much disappears for most of the books in the series until the end of book five, and barely interacts with Harry when she does show up. (Even after she supposedly got over her tounge-tied fangirling of him). The hook-up happens in book six, but then what happens? She disappears again for almost all of the final book.

Harry is my favorite character in the series, but I don't think indifference is how I'm supposed to feel about the person he ended up with. But indifferent it pretty much how I feel about Ginny, and Harry's relationship with her.
