Her track would have been a nice addition if it weren't for the pointless lesbian fling conclusion.
The only acting that stands out is that of Shahana Goswami. Even fine actors like Divya Dutta and Lilette Dubey aren't given much scope (mostly due to horrendous writing). Perhaps Bhandarkar was aware of Kapoor's limitations and had the voice-over of a pointless reporter character (one of the most annoying features of 'Heroine') dictate how the viewer is supposed to feel. It doesn't help that the character is halfbaked and one-dimensional. Kareena Kapoor in the title role hardly impresses at all. Poorly written caricatures, lacking in focus, the film doesn't seem to be able to make up its mind. Think of it as a disastrous fusion of his aforementioned films with Bollywood as the backdrop. While his previous films like 'Corporate', 'Fashion', '' etc also present a heavily biased view, the stories had more structure (as flawed as most of them might have been).
Other than the (fake) 'fact' that 'everyone in Bollywood is evil and self-centred' (according to the director), I didn't get what point Bhandarkar was trying to make.
