I would recommend a great little book by Niall Ferguson called empire, Here is the link to save anyone's fingers doing the typing: https://www.angusrobertson.com.au/books/empire-niall-ferguson/p/9780141037318?gclid=EAIaIQobChMIwurCv4eM5AIVzw0rCh0P1wCNEAkYASABEgLxsvD_BwE
It is truly a 2 point perspective of the good and bad points of colonial history. Great book, maybe it could challenge some peoples ideas on here about the apparent benevolent European saving savages from their own ways.
Sorry though not sure if it comes in documentary form.
