As a kid growing up during peak Veerappan times, during the kidnapping, all I remember about the whole thing are the features on Sun News and what the elders used to talk about. I also remember the "Veerappan ah pudika vakku illa" dialogue from Kaakha Kaakha. Given my limited knowledge about Veerappan and all the events from back then, this was a very fascinating watch.
This is a 4-ep documentary, not a biopic, about the approach that the police forces from TN and KA had to capture him. Several individuals directly involved in the process, including Veerappan's wife Muthulakshmi speak in this doc. The editing and the storytelling in worth the 3.5-4 hours. The narration is slow but worth it. The original doc has a mix of English, Tamil and Kannada narration, but there's a full dub as well, in case you're wondering.
