However, the main difference from the poem is portraying Beowulf as a flawed hero destroyed by his own negative qualities, like lust for power and unchecked male desire, which raises questions about the morality underlying heroism. Despite the superficial characterization of the Water Demons as Others, the film blurs the line between heroes and monsters, as Grendel can talk, and the dragon's human form resembles Beowulf himself, representing his repressed wishes. In turn, Beowulf and Hrothgar are rendered impotent just like Grendel, who lacks genitalia altogether, and then Beowulf ends up losing an arm like Grendel does. At the end, although the men from the film pretend to be champions against demonkind, they are ultimately revealed to be only its very originators.
