I think I expected something a bit more special. The Green Knight is certainly no ordinary costume drama or Medieval adventure, but it isn't quite as magical and/or mysterious as advertised. That didn't come as too big of a surprise (not a big fan of Lowery's previous film, and A24 certainly has its limits too), but I think I was hoping for a bigger improvement.
The film is a retelling of the story of Gawain, one of king Arthur's nephews. On Christmas day, the Green Knight is summoned and challenges the knights to land a blow on him. As a reward, they'll be given his axe, but in return to must travel to the Green Knight's chapel a year later and receive a similar blow.
Lowery chooses atmosphere over narrative, which is definitely appreciated, but neither the cinematography nor score is all that exceptional. The performances are decent, there are some memorable moments, but I wanted it to be bigger, bolder and gutsier. It seems that's just not something I should expect from Lowery in the future.
