Beware, friend, Beowulf (2007) is a subversive film, not a Christian film.Rewatched Beowulf (2007) and noticed a lot of Christian themes, which makes sense given that the poem is Christian. The movie changes things up from the poem, even flips it on its head in some places, but the message of human vanity and the redemptiveness of Christ remain intact.
-The murderer and abuser Unfirth becomes the head Priest of the Christian faith in this movie
-Beowulf scornfully says "the time of heroes is dead. The Christ god killed it"
-The coming of Christ is depicted as an end to a heroic age, and by going back to heroism they conquer the dragon, not through their love of Christ
I used to love this movie too, but the subversive elements of it are too strong. The average viewer would walk away feeling like Christianity is bad, and embraced by abusive power hungry weaklings, while the strong mourn the arrival of it, and succeed by ignoring it.
The epic poem Beowulf, on the other hand, is about 400 years old and well worth reading. Beowulf is a Christian who arrives in the land to kill Grendel and his mother, who are water based monsters who survived Noah's flood. The movie didn't depict this story.
