Brilliantly done! The casting was superb and the execution was amazing. While so much attention was indeed paid to the details, there were some that could have been better. Not taking away anything from the series, I do wish a little homework could have been done to increase its authenticity. Two things that seem anomalous to me was the use of the purple Rs.100 note that was not in vogue during the early 90s. The second is that Madras, as it was called those days was always Chennai when written in Tamil. All the buses always carried the board Chennai written in Tamil while mentioning the destination or the starting point. The buses shown here showed Madras written in Tamil. Anyway this was just an observation. Loved the series.
