I think there's gotta be some business related reason for this. Most pro's in comics start off as fans. They come at these IP's from a similar direction as we do, they want the same kind of things, they just have to deal with certain corporate realities we don't.
Same goes for a lot of the editors and managers. They were fans first, and that's why they're in the positions they are now. I mean, not everyone, but a lot of them. You typically dont end up in the comic book industry unless you want to be here, yknow? Not much reason beyond sheer love of the medium to throw your lot in with a dying industry who's customers hate everything and everyone.
Yet so many decisions are so painfully short sighted, so detrimental...Donna's the most obvious example here but there's countless others...and when we can see it, certainly DC can see it too. So what the f--k is happening? Some of the choices are clearly forced by business logic and theory. A lot of DC's choices I might not like personally, but I can at least see why it's good business, or why it would look like good business. But a lot of the time, I'm left scratching my head and digging through four years of education trying to figure out the reasoning. And most of the time I come up empty handed.
So there's gotta be some kind of business theory unique to publishing that explains some of these apparently stupid ass decisions......or a lot of the people calling the shots (whether from WB, DC's management, or editorial, we'll never know for sure) shouldn't have the jobs they do.
