That makes some sense to me. I'd give the ones you've seen the source for a shot first. The Gray Gardens one (the first of the first season, I think) is brilliant. The Jiro Dreams of Sushi one for this season is also hilarious because it still has some love for its characters. I would say that one isn't even all that laugh-out-loud funny, but it is a perfect parody and so warm that it has become a favorite. There's not really a bad one, though, not that I've seen. The Nanook of the North one gets the closest to bad, but that's just because I think it drags a bit. The half hour length really helps, usually.
