I was a graduate student in upstate New York, and one of the local TV stations carried this show.  I loved the grittiness, and how it accurately portrayed people who lived close to the earth.

It also tried to portray how some of the Arthurian legends got started.   One episode showed Arthur trying to teach a lesson in cooperation to the other chieftains.  He had a large stone rolled over a sword, and dared the others each to get it out.  No one man could.  But, when they all helped by rolling the boulder off the sword, Arthur triumphantly snatched the sword.  However, instead of appreciating the lesson, the other chieftains came to the conclusion that Arthur would take credit for their efforts.

Well, nobody's perfect, even legendary kings, but this might just be the way the "Sword in the Stone" tale began.

It was an excellent show.
