From South Asian Life:
The director tells the story light-heartedly but don’t expect direct humour. There are a lot of subtle references to real-life Bollywood characters, dialogues said in the passing and facial expressions, a refreshing change from the in- your-face slapstick humour we are subjected to most of the time. The film follows both Sona (Konkona Sen Sharma) and Vikram (Farhan Akhtar) through their journey in Bollywood, one they undertake with the understanding that nothing here comes easy. So she sleeps with a producer who promises her a big break and he has no qualms about flirting with a yesteryear actress in the hope she will cast him in her daughter’s debut project. A host of characters as well as some top Bollywood actors make an appearance in this journey. What is commendable is how Akhtar has astutely used even two-minute guest appearances. So you have Aamir displaying his “perfectionist” tendencies, Abhishek mentioning “Pa” and John Abraham talking about doing “experimental films.”
