I have been having a tough time sorting through my feelings about Zero Dark Thirty. There were well-drawn scenes coupled with unbelievable scenes (e.g. all prisoners spoke English).
In the end, it's important to understand that this is a work of fiction and that there are better documented ways to get confessions from torture.
I believe that the film didn't ask enough of its characters to question whether or not it was ethical to torture prisoners, or if it led to actionable intelligence.
