What
Delhi 6 lacks is a crisp plotline. The characterization is poor and nothing that the character does is clear. In fact no situation or anything that happens has a good reason and nothing evokes any kind of emotion.

In an impatient age,
Delhi 6 takes its time to warm up to its audience. Lacking any significant plot, we are treated to assorted vignettes of life in and around the bylanes of Chandni Chowk, and when the real story does kick in, it actually proves to be quite a (monkey) menace.

So simple from above and yet so lusciously layered beneath, "Delhi-6" does what its director's last work "Rang De Basanti" did so spectacularly.
