If seeing is believing, then we better be damn careful about what we show people, including ourselves – because, regardless of what it is – we are likely to uncritically believe it.It's sentiment I endorse, but I'd be a bit suspicious of it coming from me, or from someone likewise conservative. In fact the author is Errol Morris, writing in his blog at the New York Times. As a documentary film-maker who himself uses dramatic re-enactment as a tool, I'd say he can speak with some authority on this question.
The article is a little long, but well worth reading: on re-enactment generally, and on some fascinating individual cases. And (somewhat off-topic), if you haven't seen Morris' documentary The Fog of War: Eleven Lessons From the Life of Robert S. McNamara, then truly, you must.
