I miss the Kents, too. To add a bit of insult to injury, I feel like Pa Kent's death had already been handled better in the first Superman film and Morrison's All-Star Superman. We've traded the dramatic punch of the heart attack for Pa Kent's sickbed and a throwaway line about helping the little guy.
I don't think Morrison paid out on the promise to make Superman an edgier idealist, with the end result being that I'm not sure what defines Superman from one issue to the next.
And I say this as someone who really enjoyed the first couple of issues of Action. I just don't think it panned out the way I had hoped or expected.
