Since it's by James Robinson and Paul Levitz, it's actually been quite good so far. Just think of it as basically another parallel universe with an alternate version of the JSA (which it basically is--as the mainstream DCU is basically an alternate universe as well, really), and it's fine.

I am sure we will get classic versions of the DC characters again down the road, somehow. Till then, the Young Justice and GL shows will have to sate my "classic DC" interests...
