There are 'human flaws' throughout.
As in the poem, Achilles is dominated by a wish to be remembered as a dauntless warrior, in fact the most fearsome warrior of all time, and because of this he is proud, arrogant, and unfeeling. His insensitivity is shown by his response to the small boy who says of the giant at the beginning of the film, 'I wouldn't like to fight him'. Achilles' response is: - 'That is why no-one will remember your name.' No doubt true, but illustrative of his lack of human symapthies, even to admiring children.
This lack of empathy for others leads eventually to his abuse of Hector's body when he drags it about behind his chariot, as he can only think of his desire for revenge, not how it will affect Brieesis, let alone Hector's mourning family.
He is shown as apparently having human feelng for three only people; his mother, Patrocles, and Briesis. After King Priam comes to plead with him for the return of the body, he is shown shedding tears and learning a valuable lesson.
Paris is shown as demonstrating cowardice in his duel with Menelaus, when wounded, he crawls over to hug Hector's feet. Later, he is mortified by this, but in a scene I thought nice, Helen comforts him, saying she didn't want a hero, but someone to grow old with.
Agamemnon has so many faults that one hardly knows where to begin, but his obsession with power often leads to his forgetting his own long term goals, as when he takes Briesis and so causes Achilles to withedraw from the war, so that he is in danger of losing.
