Mists of Avalon

It's an Arthurian fantasy, with the title from a novel of the same name by Marion Zimmer Bradley, a well known science fiction and fantasy author.  It tells the story thru the eyes of Morgen le Fay, who is Arthur's sister in this version of the King Arthur tale.  The priestesses of Avalon, supporters of an ancient goddess, are dueling with the Christians for control of Britain's destiny.  Arthur is but one tool in their tool kit.  We see a lot of Vivienne (high priestess) Igraine, (Arthur's mother) Morgause (all purpose troublemaker) all thru the viewpoint character Morgen.    Poor Morgen is merely carried from scene to scene like a TV camera on a dolly, she never gets to do much under her own power.  Lot of nice camera work, galloping horses, small boats pushing thru the mists of Avalon.  The plot is complex and not really understandable.  None of the cast are familiar to me.
