Agree with you, Derek. We went to Portmeirion whilst on holiday in the area...thought it was a fascinating place. The fact that it famously does not tie everything up in the final episode, or 'explain' anything, is just perfect.
"I think progress is the biggest enemy on earth, apart from oneself… I think we're gonna take good care of this planet shortly… there's never been a weapon created yet on the face of the Earth that hadn't been used…
We're run by the Pentagon, we're run by Madison Avenue, we're run by television, and as long as we accept those things and don't revolt we'll have to go along with the stream to the eventual avalanche… As long as we go out and buy stuff, we're at their mercy. We're at the mercy of the advertiser and of course there are certain things that we need, but a lot of the stuff that is bought is not needed…
We all live in a little Village… Your village may be different from other people's villages but we are all prisoners."
— Patrick McGoohan, 1977
