Sometime last year one of the writers at DC (can anyone remind me who it was, and point me at the original quote?) suggested that they were going to use the big gear shift of Infinite Crisis to lighten up their comics a bit and move away from the grim & gritty approach that passes for "realistic" in the comics world.
This was later refuted, but somehow the idea took root in the Great Fan Unconsciousness and is still being sited as official DC policy even now. I don't think I've seen any comments from anyone who thought it was a bad idea. In fact the only negative response has been from people who thought this was happening and are now unhappy when they see no sign of it.
This isn't a pressure group demanding a change they would like to see, it's just everybody seeing an idea that seems so obvious and right that they just assumed it was happening. And now they are sad and disappointed.
We don't want a return to silver age silliness (well, we do, but that craving is satisfied by Showcase Presents), what we want is a definition of realism that encompasses the lighter side of real life as well as the darker.
And meanwhile DC is acting like the shopkeeper whose response to a request for an item they don't stock is to say "You must be the fifth person today I've told that we don't get any call for that." DC, you need to shut up for a moment and listen to the wind. It's blowing in a different direction.
