I also got back in the the Superbooks in Rebirth. Even though I don't have kids, I enjoyed reading Super Sons.
These next statements are my opinions. As far as Bendis, he Superbooks have been ok for me. The whole living separately just so Lois can write a book is just silly to me. Where's the ship that she came in on that no one seems to notice or where did she even hide it? The Earth-3 flashback didn't really need to be there. I would have been just fine with with the space adventure and be sent back after that. That could that of a Jon Superboy comic with the flashback of Jon and Jor-el in space.
