Ramesh & Suresh, the Duo of Cadbury's ad, in their first appearance meet at a shop after a long time and every time they have a bite of 5 star their memory resets. The ad was a Hit; Duo got an identity which was kind of a brand for cadbury's 5 star.
This could have continued like a strip of ads with new innovative ideas on Ramesh & Suresh, but the new marketing campaign which simply focuses on the change in packaging and leaving aside any value addition to the product or any other reason for consumers to reconnect(re-look) makes it negative buzz demolishing campaign. To put icing on the blunder the ad makes it worse and leaves no scope for any person on screen named Ramesh & Suresh.
