I can't get on board with the cosmological stuff (or any of it). There used to be a theory that Iron Age roundhouses were constructed on cosmological lines. Then everyone realised that the doors were positioned to avoid the prevailing wind and that people sat in the doorways to work because that's where there was most light.I watched 15 minutes of one episode and found it utterly ridiculous. It just seemed like silly fantasy masquerading as fact. I wish I could remember what it was.
I'm not particularly familiar with him other than that one ill-fated watch that had me pulling my hair out.
Edit: think it might have been ancient apocalypse.
