Without diversion via the questions embedded in the profession and the perception and self perception of the male geek working and academic world, I so rarely see a presenter reacting to a sense of apparent human warmth in the room, and beyond the lens, which even with the most encouraging assistance behind the lens, is genuinely hard to do. Hard enough that I think it is a classic contribution to the stereotypes of inflated ego newsreel presenters, which Hollywood loves to satirise, in my opinion because Hollywood is mocking, to their narrow and insecure view, a subspecies of acting which when done well, can so massively capture the greater audience than ever some most serious actors may manage to capture.
This is a bit more than a little bit of geek knowhow and applied thought, but I think many geeks by virtue of sheer analysis without a obstruction of a ego, could be handily outperforming the supposedly inherent talent they are "meant" to possess. It may be reaching well into "real serious" acting, very easily. I don't pretend to be a judge of that, but if acting abilities are "I know it when I see it", this is excellent acting indeed.
Edit, is not was, first line. A comma for clarity but later on.
