I almost typed this up in the comments on another blog, but I didn't want to give away stuff on other people's blogs that I could give away here instead.
I saw the movie a couple of weeks ago with a talkback from screenwriter Mark Boal after. His line
is very journalistic -- "These things happened" is essentially a
paraphrase of his response to questions about the morality and politics
of the movie. It's both true and feels like an easy dodge, and I've felt
torn ever since about whether the movie is actually interested in asking
tough moral questions it may not have the answers to, or just trying to
tell a strong character story that happens to be about really difficult history.
It does both of these things (whether the filmmakers intend it to or
not), which is what makes it compelling, but I still found it to be a
seriously unpleasant experience. Regardless of its moral or artistic integrity, it
made me sick to my stomach.
