It is not in Affleck's interest at all to discuss the politics. I can understand why a lot of people vastly hate that and judge it as lazy storytelling. To me, it seems as if Affleck is aware of what plays to his strengths. I think he would be out of his depths if we had had a script that focused on the domestic implications of the whole thing. The political implications are indeed unimportant for Affleck, who focuses on the human drama.
And I think the outcome is solid. This is not the best film of the year but the Oscar winner never is anyway.
ZD30 is about the politics and not only the kill.
Argo is about the kill and not the politics.
Make of that what you will. I think it is clear that Bigelow had a far more exhaustive and difficult task. But for someone who is not a film director (ouch), Affleck's output is not terrible.
