Don't be fooled by critics and reviewers praising this film's cinematography, the director's courage, or making bold claims about how beautiful the visuals are. This was a horrible movie from beginning to end. As others have stated, it is long, boring, and filled with scenes that either make no sense or drag on forever - or both. To say the director favored style over substance is a massive understatement and might suggest it’s worth sitting through just for the pretty visuals. Trust me, it isn’t. I don't care if it's an A24 movie. It's a bad movie.
Why is it so bad? Because it wastes an opportunity to tell an excellent story. This film's version of Gawain has little in common with the brave and virtuous knight from the poem. Frankly, it isn't worth the time or effort to tell this Gawain's story. His characterization as a hapless rogue, doomed to suffer the consequences of biting off more than he could chew, squanders the rich source material on which his story is based. When coupled with incoherent scenes and supporting characters that are barely more than talking props, trying to sit through this film is a real chore. For those who can stick it out, you’ll be rewarded with a lackluster climax, no discernible resolution, and morally ambiguous themes.
Unfortunately, that's just scratching the surface of all that is wrong with this movie. Lighting. Makeup. Casting. Score. Messaging. Symbolism. There's a lot to hate about this film.
To be clear, this is one of the worst movies I have ever sat through. Watching paint dry would be a better way to spend two hours and you'd probably take more away from it. Seriously, it's that bad. Do yourself a favor and read a modern translation of the poem instead.
