What's the Skinny on Skinny Pepsi?

 Diet Pepsi Debuts its Sleek, New Look at Mercedes-Benz Fashion Week

"Diet Pepsi has a long history of celebrating women through iconic fashion imagery seen in our infamous and historical campaigns, and we're proud to continue that tradition as an official sponsor of Mercedes-Benz Fashion Week. Our slim, attractive new can is the perfect complement to today's most stylish looks, and we're excited to throw its coming-out party during the biggest celebration of innovative design in the world."  - Jill Beraud, Chief Marketing Officer, PepsiCo

This packaging seems to make complete sense from a Customer Insights standpoint. The tall, thin package mimics the suggested product benefit. We should non-consciously transfer the perceptual lightness of the package shape to the can's contents. The colors are light, the typeface is light; I mean, even the 0 in the zero calories looks thin!

But then I started reading that some things in their advertising campaigns may be too thin...

At what point are people/critics/groups reading too much into an advertisement?
