i like how arthur's adopted father and older brother in excalibur aren't douchebags.

my introduction to arthurian lore was in the disney movie the sword and the stone. in that movie, arthur's father and older brother are massive asshats to arthur, probably for the purpose of making arthur more of an underdog. nowadays, my favorite adaptation of the story of king arthur is john boorman's film excalibur. and, in that movie, ector and kay are loving family to arthur. kay, arthur's older brother, almost immediately gives arthur credit as the one who pulled the sword from the stone. ector, arthur's father, is grooming arthur to be kay's squire at the start of the story. he gives arthur some advice on how to be a good squire and is patient and forgiving. after arthur learns the truth about his origins, ector says that, while he originally took in arthur due to his fear of merlin, ector came to love arthur as his own. and, once arthur forms the round table, both ector and kay become members. it would have been super easy and cliche to make ector and kay assholes so as to make arthur more of an underdog. but having him have 2 positive role models actually makes narrative sense. where do you think arthur got his good qualities from?
