At a time when there were mainly formula films that got made in Bollywood and Anurag kashyap was struggling to get a proper theatrical release of his first film, there came this movie that I watched recently 15years after it got made(it came out in 2006 acc to IMDb) and I have to say, this film felt very fresh and contemporary. First off you have to see this for the supporting cast ,all those character actors of 2000's who have made their mark in Hindi cinema like vinay Pathak, saurabh Shukla, great cameo from manurishi chaddha, rajat Kapoor(who directed the film), and few others.
Ranvir shorey and konkana sen playing husband and wife (in real life also they are married) are a treat to watch. And the wife swapping thing(don't worry, not a spoiler as its name suggest it :) ) is such a practical plot.
Give it a shot , it's worth it.
