I mean, they could have shown Bill being cool on-screen; it's not like JKR doesn't know how to make a character incredibly badass. See, for instance:
Bill's a minor character plain and simple. But I thought he earned the "cool" description when he stood by Ron in book 7. Bill knew Ron screwed up, Ron knew he screwed up, but Bill (and Fleur) took him in when he had nowhere else to go. That's what a brother should do. On the other hand Augusta was just mean to her grandson when he was a young kid... becoming proud of him later (when he actually was a badass) doesn't make up for that.
