I was shocked by the previous review because I loved this film. Could be differing expectations; mine were not only met but exceeded. This psychological drama set among the professional world of young, educated up-and-comers in Mumbai is one of the most "un-Bollywood" of Bollywood films I've seen, and I've seen many. Farhan Akhtar plays Karthik, a bright but painfully shy & insecure man who suffers regular abuses by his boss and is virtually invisible to all the other employees at the construction company headquarters where he works. Out of the blue he begins receiving phone calls from another "Karthik" which offer him support and advice, improving his life. He eventually becomes completely dependent on his connection to the caller, and when the calls turn dark they threaten all he has achieved.
The screenplay and directing by 31-year-old, first-time writer/director Vijay Lalwani were taut and understated, which to me is far more effective at drawing the viewer into the story than the excesses of the typical masala Hindi films. The music by Bollywood veterans Shankar-Ehsaan-Loy was spot on, not showy for it's own sake but lending uncannily perfect support to the story in every scene, even down to the incidental passing scenes. Deepika Padukone is stunning as usual and her work gets better and better. She plays Shonali, Karthik's long-desired love interest, with a nice balance of vulnerability and coolness. But it's Farhan Akhtar's film, and he's a revelation here, adding the perfect comedic and dramatic touches to Karthik to steal your heart and send you on an emotional rollercoaster. At 135 minutes, it's also on the short side for Bollywood films, and as wrapped up as I was in it, it flew by.
