I think the way they set Greg up as the dopey, awkward one suggests to me he'll be the big transforming family member who'll probably be running the empire by the end of it's run.
Roman and Gerri are my fave characters. I did like shib at the start, but have slowly gone off her as her character has changed.
My only concern about the show is the same problem suits had with Mike Ross and this one has with Logan - how many times can they keep going to the "nearly gets ousted then comes back" and still keeping it fresh and interesting.
