This is an observation rather than a criticism: the woman playing young Carrie appears to be channeling the Sarah Jessica Parker interpretation of the character.
Ummm... Why wouldn't she? Isn't SJP the character she's playing?!
I recorded this out of curiosity but I've not watched it yet. Using the post-9/11 skyline was just dumb. First of all, it's been 11+ years now, I think people can handle seeing the WTC in an establishing shot of a show taking place pre-9/11. It's really just a time/continuity nightmare. Wouldn't it have been easier to just make establishing shots of NYC that don't include the WTC part of the skyline?
