Query: Great, but unbelievable, story

One of the most compelling treatments of the Arthurian legend, Excalibur traces the classic tale through the birth and rise of Arthur, creation of the Round Table, the fall from grace, and final redemption of the Holy Grail and battle with Mordred.Boorman spared little effort to create a visually rich tapestry, but this was the film's undoing; example, as they at dinner around the Round Table in full armor, the knights look more like a 12-pack of Coors Silver Bullets that brave knights.Still, the film uses symbolism powerfully and effectivly, such as the land being reborn as Arthur rides past.Great performances by Patrick Steward, Nicol Williamson, and Helen Mirren as Morgana.If you love the Arthurian legend, you'll love Excalibur.
