I love, love, love these characters and have since the beginning. I have always said I can never get enough SATC, but I was wrong. It could have been an hour shorter and still told the same stories. Carrie recyclyed outfits from the HBO/TV days, Charlotte was too whiny, Samantha was menopausal and Miranda was...actually Miranda was fine. She was the only one that didn't annoy me.
Surprise cameo by Ron White (one of my fav comedians) as Miranda's a-hole boss was a treat.
I would say if you love SATC, you will like this movie just fine, as I did. If you are not a die hard, you will most likely come out of the theater wondering where the last 3 hours of your life just went.
