Take your common sense and fuck away off with it, Campbell - this isn't a job or anything where common sense has a place, this is the magic wonderland of fairytale rainbows and lemonade waterfalls that is comics. After all, common sense might suggest that pandering to a shrinking fanbase of long-time diehard comics fans with a memory of more than five minutes is utterly at odds with "continuity should not get in the way of telling a story", but this is comics. We hate the comics form and we want our comics more like films, but we also want them to stay the same while changing, too.
In regards to your comment about superheroes in real time - check out the Comic Book Resources boards whenever a thread comes up about the age of Franklin Richards. It's either hilarious or deeply disturbing what follows.
But anyway, the problem with this DC reboot as I see it is twofold:
1 - this is just as much a jumping OFF point as it is a jumping ON point for readers, which is why no-one has done it before, certainly not a company whose main problem is not talent but in-fighting among staff and deliberate undermining of talent among management.
2 - DC have no shortage of writing talent but their books still come out mostly poor and no amount of gimmicks or name talent will change that because the management structure and creative process remains exactly the same after the reboot. Those books are poor now and they'll be poor later because nothing will actually change.
I don't want to buy DC books, so it's nice of them to give me a tangible point where I can stop caring or following what happens in them.
