Casey Malone’s review published on Letterboxd:
Saw this at the Los Feliz 3, where the guy doing the intro referred to it as "Elaine May's darkest comedy" which apparently gave the crowd permission to react to this like it was an extremely depressing sequel to Superbad. There are funny elements in this movie, especially around Ned Beatty's beleaguered hitman, but they were hooting and hollering the whole time, even at scenes that are demonstrably fucked up. Wild.
That being said, perfect movie.
EDIT: I was just reminded that at one point Peter Falk said, "Sorry, but I hate you." and then in a near silent room someone's iPhone heard "Siri, I hate you" and replied, "That's okay." That actually was very funny but I don't think it was part of May's vision for the film. Impossible to know without asking her.
