Its a great film, but Boorman tried to please everyone, setting it in the 6th century but having them doss about in c14th century plate. It realy dont matter much in the long run, its dont matter wether the directors of such things stick to the legends or "lore" or totally change them - it comes down to how entertaining the piece is. The new BBc Robin Hood falls down on so many levels - yet its still entertaining to me, so I watch it. Excalibur is the same. Merlin I didnt find so entertaining so then all the changes and innacuracies etc started to matter too.
