Confessions of a what-a-holic?

I'd like for the marketing department for the film "Confessions of a Shopaholic" - which, given the current economic crisis, may be the most poorly timed movie in the history of poorly timed movies (just beating out "Citizen Kane," which was released just as audiences were exhausted with hyper-literate and brilliantly photographed thinly disguised parodies of bloviated media magnates) - to explain, exactly, what they were thinking with their campaign for the film. (Actually, I pretty much know what they were going for; I'd just like them to admit it.)

First: Isla Fisher's facial expression. Fisher was absolutely hilarious in "Wedding Crashers," until the filmmakers decided they didn't need her to be so anymore, but it's hard to figure out what she's trying to convey here, if in fact she's trying to convey anything chaste.

Her expression seems to read, "OMG! I've just purchased a load of overpriced, superficial consumer goods that I can't possibly afford! How did that happen? LOL!"

However, there's a load (pardon the expression) of individuals who aren't violently misogynistic, as well as a wealth of literature that explores the subtext of attractive women with blank expressions and mouths wide open that divines prurient intent. And Fisher's relationship with Sacha Baron Cohen (best known on these shores as "Borat," whose semi-exposed male member was comically extenuated by wishful-thinking censorship in his brilliant and wildly popular 2006 film), only suggest to those viewing this poster: You do the math.
