yeah, i've not heard too much about the storyline (mostly cuz all i've seen are the trailers, which were confusing as hell) but from what i've gathered, it has seemed like a continuation, which i thought was odd because like you said, the finale ended things just fine.I resisted it at first, since I wasn't that thrilled with them picking the story back up after tying things up so perfectly when the show ended, but eh, I'm over it and I'll always look at this as a nice little add-on to the series. I'm still not too thrilled about Jennifer Hudson as Carrie's assistant, though.
and yeah, the jennifer hudson thing stuck me as a bit odd. i guess i just don't care for her
