Movie review: Kahaani - In search of her missing husband, a pregnant woman take a journey from London to Kolkata but adding to suspense, everyone she questions, from guest house owner to the HR head of the company where he worked, denies having ever met her husband. It's a remarkable suspense drama which keeps you on the edge of your seat through out the time. Everyone in the film acted well. Be it the lousy LIC agent - cum - remorseless hitmen or hard-nosed IB man, Mr. Khan! All fitted well in the role. It's out and out Vidya Balan movie. she has proved again that she can carry a movie on her shoulder alone, without needing a star actor for commercial success. Her pretty looks, vulnerable, harmless and helpless acts are a treat to watch! It's a movie where you don't realise till the very end who is manipulating who. Parambrata Chatterjee as Rana and Nawazuddin Siddiqui as Mr Khan are new faces to watch out for. Last but not the least - camera work is awesome! Kolkotta never looked so beautiful, vibrant and colourful. I am so tempted to visit the city during Durga Puja some day. Rating 7/7 (1-Avoidable, 2-Bad, 3-Below average, 4-Average, 5-Above average, 6-Good, 7-Must watch)
