I just read the story in which she was introduced a week or so ago (I read Runaways in digest form), and I wasn't terribly impressed. Based on what I've seen posted here things haven't really improved, in fact she seems to have become a more light and naive interpretation of the 'fish out of water' than her more serious and world weary previous characterization, and I'm not sure that's a good thing.
Of course I'm judging based on scattered scans, so yeah...
