The thing that frustrated me most about "Supergirl" is that you would think that Clark would pursuit his newly discovered and arrived cousin (you know...find out information about her) . They had that initial meeting then poof, Kara kind of gets wrapped up in adventure after adventure (which of course the writers intended, so I get that part) but no sign of Clark. I guess they wanted to do the meeting a little different than typical, which is something I do respect, but I disagree with the way they've handled her arrival.
I think the Superman Family self contained event is supposed to start soon...and they've teased a reunion between the two, and I understand she's supposed to settle down and get cast members, so we'll see. I've not given a second chance to books that I've dropped yet, and aside from you, I've not really read anything real positive about Supergirl other than the art.
