That's what I'm beginning to wonder after recalling this page on the Flash fansite about Cobalt Blue
that talks about the "evil twin" storyline that Waid did, taking an earlier story and character
written by Cary Bates and using it as an excuse to "turn and loop everything upon itself." I'm not going to quote the text, since what the drunken doctor did is something that even I have a limit to putting on this website, but having mentioned the drunkeness of said doctor, I must say that that is one of the most forced-sounding storylines I've ever heard of. It also sounds very contrived. But the main problem is that it's...violent.
People can justly argue that the violence featured in Geoff Johns' comics, Flash included, was uncalled for. But at the same time, they'd be advised to bear in mind that Mark Waid may have ruined the Flash long before Johns did, as was decidedly the case in the latter part of his run on it.
