I agree with your point, mostly, but the problem is that there isn't anybody who can do that anymore. Even if we assumed your ideas were 100% perfectly right, there are a million different ideas of what's 100% perfectly right that may-or may not-be as valid as yours. I like some of your ideas, MOTA, but I like a lot of ideas, and we aren't in charge. In fact, I'm not sure anybody is in charge.
Continuity is in a constant state of being rewritten, retconed, revised, retroed, retreaded, reviled, reevaluated, revamped, stomped on and just plain dumped, and it's been going on as long as comics have existed. Some hot shit writer comes along every few years and coms up with a different spin, putting whatever previous writer's ideas in the toilet. I used to pay a lot of attention to continuity, but years ago it meant something and now they put a yogurthead like Eddie in charge and it doesn't mean anything any more.
