[afterburner]

If you watch it all the way to the end (or skip towards the end if you like), she does mention this legacy is a result of exaggerated stories not even written down by him, but related second hand by people around him with their own attitudes (and financial inventives). He was probably not an angel, even a bit of a cocky dick maybe sometimes in the way of the times, and perhaps a bit vain, but stories related second hand when he was probably joking around don't necessarily represent the true history of his life.

She has good things to say about him in the end, from the evidence of his actual behaviour, like doing education outreach and loving his wife.
