Your opinion is well made and I agree that we would be poorer without the documentary ever being made. In this digital age, would it be so hard for media companies to go back and correct errors like this? That way people might watch it again via re-runs, DVDs and iplayers?
In my experience of being in documentaries in the past (in a far more minor way than JN, I hasten to add!), the media production team would often take offence to any criticism of their final cut - which would kind of make a nonsense of a final showing! So I say this in support of JN, that it is often the inflexibility of the documentary production team that serves to introduce such errors.
Just a thought - I'll zip-lip for now.
