As I expected, the movie is attracting aggressively bad, and somewhat funny, reviews.
For example, the Salon review notes this about the marriage of "Carrie" and "Big":
Big yearns to lie on the $12,000 leather couch, get fat on takeout food and watch the Weather Channel on his new flat-screen TV -- the character seems to have bypassed his 50s and gone straight to supper-at-Denny's age since the first SATC film -- but through various forms of time-honored feminine coercion Carrie extorts diamond jewelry out of him and drags him to restaurants and red-carpet premieres night after night. Oh, the suffering! They're like the wounded couple in Bergman's "Scenes From a Marriage," except with millions and millions of dollars and no souls. When Carrie asks Big, "Am I just a bitch wife who nags you?" I could hear all the straight men in the theater -- all four of us -- being physically prevented from responding.And that's one of the milder passages from becomes an increasingly savage review.
Surely it's the end of the "franchise".
