Re: Have we witnessed the death of intelligent TV?
As for ancient aliens, well the theory may seem far-fetched, but it's worthy of a place on a science channel since it's a fact that based on Iron Age/Bronze Age/Neolithic technology, we don't know how some structures were built.
It is far fetched.
What it is not is an actual theory with any kind of scientific credibility. It no more belongs on TV than Loose Change or Zeitgeist do. I remember one very funny documentary that was dedicated to debunking this kind of nonsense, but besides that (or I guess a history of the evolution of the idea, van Daaniken and all) I can't think of many good ideas for documentaries around it.
