I was just about to watch this one. I loved Nightcrawler. I'll watch this one and come back with more to say.
About the satirical aspect of the movie, satire does not always make people laugh. Humor may be one aspect or tool through which the satire is carried out. Others are irony, exageration, and ridicule. Often times satire actually upsets, and if this movie combines satire and horror, then the upsetting aspect may impose itself over any humorous intent that it may or may not have.
