This much loved thriller is rated very highly by most people. I enjoyed it a great deal too, but more as a campy entertainer with fun songs. Amitabh Bachchan is very good in both his roles. The film is hurt by its modest budget but rises above it by focusing on histrionics. Pran has a great role as a circus performer. Zeenat Aman provides the glamor element. The soundtrack is still very popular and was partially copied in the Shahrukh remake. While the remake is admittedly stylish and with better production values, Amitabh's 'Don' remains more entertaining to watch.
Overall 7/10
