I was going to watch it when it ran on Sunday.
Having read the reviews in the UK press, I doubt that I will bother. I will, however, try to watch Grand Tour when it launches.
It sounds like (as already indicated by the US and Aussie versions), much of the entertainment value of the show was in the individual presenters and their chemistry/ability rather than the nature/format of the show.
I think the BBC may well have trashed the value of its biggest earning production.
