Grendel’s attacks are targeted specifically at Hrothgar’s men as a response to past trauma, rather than random malice.
The film follows the warrior Beowulf as he leads a troop of soldiers to assist King Hrothgar, whose kingdom is being terrorized by a murderous troll named Grendel. Unlike the poem, where Grendel is a mindless monster, the film portrays him as a sentient being seeking for the murder of his father by Hrothgar. Key plot points include: Beowulf & Grendel YIFY
