Here's a review round-up of the film
Deadline: Spinning off from the poem, Sir Gawain and the Green Knight, Lowery has shortened the title and turned it into a cinematic journey to remember...Fans of epic tales like Lord of the Rings will find themselves transfixed with this intelligent and thought-provoking trip back to that time.
The Guardian: That this eye-popping visual bounty would be a mere side attraction attests to how much movie Lowery jam-packs into two hours, the untamed gorgeousness easing us through the early-Christian arcana, tangled personal development, and occasional formal experiments with time. To disguise a film so artful and boldly uncommercial as mass-market entertainment for those still hurting from Game of Thrones' conclusion " there's your act of heroism.
IndieWire: Surreal, stoned, and glistening with a layer of heavy metal realness, David Lowery's medieval adventure is a chivalric romance for the ages.
The Hollywood Reporter: An otherworldly Arthurian legend that owes as much to The Seventh Seal as to Excalibur, David Lowery's The Green Knight is a dreamy mood piece that retells the classic hero's journey as a hypnotic tale steeped in dark magic and supernatural horror.
Time: There is no lettre flambÃ©e, specifically, in the late 14th-century poem Sir Gawain and the Green Knight. But it's part of the embroidery writer-director David Lowery uses to fill out his extravagant unicorn tapestry of a movie, The Green Knight, a detail that makes this ambitious adaptation feel both lived-in and magickal, with all the self-aware grandiosity that superfluous ancient k implies.
