The Killing of Two Lovers (2020) review

Married couple David (Clayne Crawford) and Nikki (Sepideh Moafi) have "come to the agreement" that they should be in an "open relationship" ... which means Nikki's busy sleeping with Derek (Chris Coy) - who works in the same building as her - and has David, without a partner and in a state of extreme duress, contemplating killing both of them.  I like the aesthetic of the project - David is literally and figuratively "boxed in," the mountains of Utah loom overheard like the actors and actresses are standing in front of a painting - but it's extremely underwritten: many of the scenes feel like they were improvised and sort of ramble on, trying for a sense of "naturalism" that it doesn't quite achieve.  It ends in the most perplexing way imaginable: is Machoian arguing that getting pummeled by your wife's boyfriend is the best way to save your own marriage?
