They're ghastly; I couldn't watch for long.  You can, of course, buy a DVD on Steevens' website.
Whoever really built Stonehenge have been spinning in their graves for some time now.  "Superconducting fool magnet" is the best way of putting it I have ever read. 
I have a really bad habit when I encounter Pagans with names like Merlin and Oberon and Brigid and Morgan.  A big snort of laughter and the words "You ain't him/her!" fly out so fast I no longer have much control over it.  Yo dude with the sword--You ain't him!  I know you ain't King Arthur because I know a chick in Jersey whose 7-year-old son is King Arthur.  Just ask her!    
  And they wonder why I very rarely admit to being  something of a Pagan.
