Rose, I think you are too harsh.
I think I can detect the dead hand of bureaucracy here. 'Sorry old boy, just not enough interest for more than a couple of parts, keep it down to under two hours, OK?'
The scope was huge and while we experts can criticise the addition of this or the exclusion of that, I think on balance it was a brave effort pulling in much rare footage.
Yes, we would have done it differently, but would we have done it better?
