It's...interesting. Honestly though, I don't find it that enjoyable. It may well be the next DCnU book I drop. In the first issue he was still basically in a test tube, so he was a completely blank slate. We're now 8 issues in (I think?) and he still hasn't formed much of a personality to speak of. It feels a little tedious. If you haven't started reading it, I'd wait a while and then start reading from #1 so that at least you know it's going somewhere.
They're playing up the TK way more than before. He's really not (at this point) a Superman clone, but something entirely different from a powerset standpoint.
