how did his movie get nominated for best picture but not him for best director of the best picture?
No one knew Argo was going to take best picture until it started sweeping all of the other awards before the Oscars. That's when it became the favorite. That's when it got the votes.
That's how this shyt works. Every year. The voters are only human. Easily influenced.
Did Argo deserve best picture? It's debatable. I saw all of the nominated movies and other than Zero Dark Thirty, Argo is most deserving.
Was the direction worthy of a Best Director nod? Not over Ang Lee. Not in my opinion anyway. Not when you consider the directors job. Ang Lee's task was much much tougher than Ben Afflecks.
Where I will hand it to Ben though is that he was able to take a bunch of different tones and meld them all together. The anger and seriousness in Iran, the lighthearted play in Hollywood, and the politics and buffoonery in Washington. All while keeping the tension up. But I'd credit a lot of that to editing and a good screenplay...not direction or decisions made on camera.
Am I hating? Nah, that's a Boston dude right there. I'll never hate on my own. Just don't think he deserved the director award.
