The film is a retelling of the Arthurian legend of Sir Gaiwan and the Green Knight. While several characters' names are not mentioned in the film, they can be inferred by common knowledge of the source material--King Arthur, Lady Guinevere, Morgan le Fey, Merlin, etc.

In that capacity, there are several women characters who are key to the plot, however, none of the characters outside of Sir Gaiwan, Winifred, and Essel are officially named AND also called by name in the film. The other main characters who would be otherwise inferred are otherwise officially listed as simple roles like "King", "Queen", "Mother", "Magician", etc.

None of the women characters speak to one another (outside of a ritual cast by Gaiwan's mother--the unnamed Morgan le Fey--and her attendants, the three sisters).

Technically true (that the test is not passed), but there is little dialogue in this movie and most characters are not named. Besides, the mother is the most powerful figure in my opinion. So certainly no example of misogyny.
