This is one of the best Indian films i have seen, Bollywood is not known for producing detective stories but they managed such an interesting movie. It was brilliantly detected, decent background music, suspense till the end, nice script, good plot. In a detective story one has to develop every single character from a driver or a neighbor to the detective itself, and the director and writer managed to do so in this. The dialogs are brilliant and can be used in everyday lives. BUT, there is one thing, after the film ends, the director, writer, actors and every body tells us about the making of the film and all. They tell us that it took them a lot of days to build up Samrat's character in the film, they considered a lot of things and thought a lot before giving a summer of the character to Rajeev khandelwal. While the truth is, all they did was ask Rajeev to closely observe Benedict Cumberbatch's character and copy it, which he did. Same attitude, same lifestyle, same coat, same way of setting the collar of the coat. They should have at least told us that they were inspired by the brilliance of Benedict Cumberbatch. Otherwise, as a whole, the film is awesome, suspense till the very end. The actors did great job.
