I think it's past its expiration date. Watching four self-centered women has grown boring. The sex is no longer enticing, they've all hooked up with husbands. The only reason to see the movie is the glamor of the city.
On a more interesting theme, what products will the movie make popular (other than young girls moving to NYC)? Before the series, Magnolia Bakery was just a shop that sold dry cupcakes. When it was mentioned on the show, people started lining up to get in the store to buy dry cupcakes.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
