I think the documentary kind of presents you with 3 "types" of indie developers, and maybe leaves you asking which one would you want to be more like. To be sure, all 3 games are excellent in their own right, and I'm not in a position to criticize them directly simply because I haven't made any game of that calibur, and not for the lack of trying.
For instance, Jonathan Blow(Braid) seems fairly balanced, although quite an introvert(as many of us, I guess), probably a bit pretentious, and he is known for making somewhat grandiose statements and analysis of the state of gaming, its relation to the "human condition", indie vs "AAA" games and so on.
On the other hand, it is probably known that Phil Fish(Fez) is, well, kind of a mess. As of now, he has abandoned the development of Fez 2 because of a quarell he had with a video game reviewer, and the subsequent twitter flamewar. So it seems he does invest an unhealthy amount of emotions into this whole ordeal.
And lastly, Edmund McMillen(Super Meat Boy) strikes me as the developer who is just passionate about making fun, good games, and that is it. His game is the least "pretentious" of the bunch, just excellent platforming goodness with a deep understanding of the genre, and he's also the one who went to make a second indie "hit", with the Binding of Isaac, which is also pretty awesome.
So I guess it's not strange that we all liked "the guy with the cat and the wife" more
