Reminds me of "The Lobster". A number of reviewers called it funny and a black comedy. I seriously wondered whether we watched the same movie.
So it was sometimes very funny, but was also sometimes very dark. Let's call it a… black comedy.
More like it was almost relentlessly melancholy, peppered with some horrific violence, agonizing conflict, and the occasional brilliantly written, darkly funny moments. Humor was honestly a tiny fraction of the total time.
You can call it whatever you want, but I'm certainly not going to recommend it to friends as a black comedy. That's a surefire way to set them up for disappointment.
The melancholy, loneliness, and utterly pointless violence far outweighed the occasional laugh.
