Rana is definitely eye candy but he cannot seem to act to save his life. Also the fact that he is named Joki in the film, which is hilarious. The film had great promise but all that was glossed over unfortunately.
So maybe "Aaj mere liye chair kheench raha hai, kal meri skirt kheenchega" signals the official massacre of some awesome RDBurmanness and graceful Zeenat Amanness. And maybe Dum Maro Dum being promoted through a skimpily-dressed Deepika Padukone gyrating at a rave party (and through sundry tabloid-worthy "news items", including celebrity link-ups and "legal tangles") is like promoting toothpaste using salt.
Indeed, it is probably now tough for viewers to see Dum Maro Dum as an entity by itself, without having to place it against the backdrop of what is largely irrelevant ....
