Personally I thought that it was a great programme, but it's probably worth bearing in mind that it's possible to enjoy a programme / documentary even if the subject is not somebody to whom you can relate. The best documentaries / biographies are interesting because you can't relate to the protagonists, so long as the documentary gives you something by which to understand why they did what they did.
For me, it was a fascinating snapshot of the sport 'at that time', not this, that opened up a little of how the peleton works, the camaraderie that operates outside of team borders, and the rules of fair play and honour within the professionals that the peleton operates by even when at the same time ignoring moral blindspots and contradictions (such as the drug taking).
I also liked the jersey sponsors – Gitanes, Pelforth, Mackesons … a different time indeed with perhaps a very different moral compass.
I do fail to see why in some peoples eyes enjoying the documentary means that the subject is an icon, to be admired etc.
