I do love how the naysayers despised DC at the possibility of rebooting, until it turned out they weren't really rebooting, now all of a sudden it's a reboot that was crucially needed and keeping things as they were is an unacceptable failure. The grass is always greener and all that.
To me, it seems that much of the people who are proclaiming this a massive failure and cutting all ties with DC, yada yada, are the ones who were pretty much determined to hate it in the first place. As far as the people actually reading are concerned, the response amongst the vast majority seems to have been positive. Those excited about the relaunch largely remain so, while I've even seen many of the skeptics won over.
Are there problems? Sure. There are continuity headaches it's probably best not to think about. But really, after all the hype of the relaunch, things will be as they've always been: some comics will be great, some will suck, and there'll be stuff that doesn't make sense. And from there, you have a choice to let continuity in a fictional universe poison your enjoyment for everything, or to simply focus on the stuff you like and not bother with the stuff you don't.
I think Paul Cornell said it best in a recent interview:
"The idea that one reads comics as a sort of news report from a parallel world, where the only interest to be found is in how much a story has to do with 'big developments' is, I think, gone with the old universe. We're just out to tell a good story."
If you're reading the New 52 to get immediate answers on how everything fits into a neatly categorised continuity and chronology, you'll likely be sorely disappointed. There are a lot of people who seem to require from comics a soothing sense of sameness and everything returning to their ideal status quo from their particular era of choice in order to appease whatever OCD tendencies they may nurture. But for me, the most important thing is that, for the first issues at least, DC has produced a high ratio of GOOD COMICS. Strong writing, quality artwork, with characters I'm interested in.
All I ask of DC is to be entertained. They don't owe me anything, other than the entertainment I get in exchange for a comic I purchase. And if a comic ceases to entertain me, I simply cease to buy it. If all comics cease to entertain me, I'll cease to buy them. If you don't like, don't read. That's not an attack, it's a simple statement. No ones forcing you to buy comics you hate month in and month out for years on end. It's not Marvel and DC's fault if you're a sucker.
