Still, the show and its connection to the Carrie Bradshaw of SATC it's gonna start now, if there's a third season, which i doubt. At first i was excited about seeing a young Carrie, having her first time, her first Cosmopolitan, buying her first pair of Manolos (that hasn't happened yet), but if anything, that's gonna happen in the next season, because that would be Carrie living in the city and finally cutting family ties (let's hope). Because, i don't recall Mrs. Bradshaw talking about her sister on the show but once, and that's it. Also, it would mean (i'm guessing) the introduction of several characters like Stanford or even Miranda and Charlotte, which i would love to see (even though the Samantha portrayed wasn't really my cup of tea, she was too trashy and i still think that AnnaLynne McCord would have played a much better Samantha Jones). And we would see a grown up Carrie, not in highschool anymore and becoming self-absorbed like she is, which started to happen in the final episodes of the second season.
So time will say for this show, i haven't read the books but i hope what comes is more promising that this past two seasons, or at least, more oriented to the first show because that's what we're all expecting without having too many expectations about it.
