About Wally...after reading why the change was made, (they admit it was a "diversity" thing), I've come to the conclusion that DC is either being run for the guys putting it out, or they're trying to guess the market rather than simply going for good stories.
Diversity's fine, but like anything else in a story, you can't force it. You have to let it develop naturally, rather than ramming it down reader's throats like DC feels it must. Frankly, it bespeaks their lack of confidence that minority characters can fly on their own. Sure, there are relatively few minority heroes in comics, but that's a natural result of the medium having been written for a certain audience for almost 70 years now. Creating new characters is the way to go, rather than changing existing characters just to meet an arbitrary management goal. Though evidently DC feels themselves not up to that task, and hence the short-sighted short cuts it feels it needs to take.
In general, it feels like they've abandoned solid story-telling in favor of cheap gimmicks. It's rather ironic that perhaps the most critically acclaimed, and certainly one of the most hyped book of the prior decade for DC, New Frontier, probably couldn't get published these days there, precisely because management's issues would get in the way.
Honestly, throwing grimdark and outreach by fiat isn't really a plan. Good stories that advance DC history mixed with new creative input and new characters are a plan. But then DC does seem to be embarrassed about its history and tradition, and thinks a return to 90s Image story-telling is the answer.
