King of Kong was an amazing movie, period. But! I do believe it was Michael Moore-ish in the way that it was edited. Billy Mitchell seemed like the ultimate villain in it, and I think that was probably unfair. Also worth noting was there were other people in the mix for the high score -- one which (if memory serves) even nabbed it before Wiebe did -- and they weren't mentioned altogether because they makers wanted one villain, one hero.
It was also interesting in Nibbler to see Billy Mitchell again, of course, and he seemed much nicer. (Ie. the makers weren't out to make him look like a villain.)
One unsung plot mover is Walter Day (the Twin Galaxies dude) who is so earnest and nice, it is easy to overlook the fact that he is the real villain! (He blurs the rules in Kong and Nibbler to certify the winners he sees fits to choose.)
Note 1: Whether he uses "creative editing" or not, I love Michael Moore.
Note 2: I am sure Billy Mitchell *is* sort of a villain, but not of the magnitude he appears in Kong
Note 3: Creative scoring aside, Walter Day seems like a legit nice guy
