Here's one thing though - did we really want Obadiah Stane to be the main villain in every single movie, aside from Captain America: The First Avenger which was set many years before? If he had survived, he'd be the villain every single time and it would be repetitive. There'd be no Ronan, no Zemo, no Ultron - no Loki. So isn't it more interesting to have a different main villain each time? By making most of the villains one-shot, this gives them the freedom to use more villains from the comics, because there's as many villains there as heroes.
