**** With A Ghost Story, director David Lowery demonstrated he was a master of dreamy wonderment. Yet that film never hinted he was capable of creating The Green Knight, a romantic fantasy so overwhelming it leaves you shivering in awe of cinema’s possibilities. Dev Patel stars as Sir Gawain, a callow adventurer who must repay a debt to his nemesis, the Green Knight (Ralph Ineson). As their final confrontation looms, Gawain wanders, encountering giants, a talking fox and a noblewoman (Alicia Vikander) who challenges his sexual timidity. Vikander also plays Essel, a sex worker with whom Gawain is in love, creating the impression that a single soul is guiding his journey in different forms. All of this strangeness makes perfect sense in Lowery’s universe, which modernizes the 14th century epic poem Sir Gawain and the Green Knight. While Gawain hungers for greatness, Essel asks him, “Why is goodness not enough?” The Green Knight matters, but not as much as Gawain’s acts of compassion, like helping a violated spirit (Erin Kellyman) find peace. It is possible to simply bask in the film’s surreal visions—like a beautifully haunting shot of Gawain and the fox walking along a ridge at night—but the wisest moviegoers will also cheer its rejection of hollow patriarchal glories and embrace its conviction that goodness is more than enough.
