Listen. I'm a writer. Done a lot of acting, free and for money, and I've seen and read a lot of plays and movies before and after. My family was in show business and movies--some still are. Plots have conventions, and a certain type of show has a plot that makes fun of conventions. It's a thing.
Every plot element in this movie is set up to be blown up. Notice that it makes you laugh at HER, slapstick-style, for killing the guy. This isn't by accident. Think about it. This could never happen in a PC play or movie--where Lefty heroes are noble and magical, and never clueless. This guy arranges his characters like balloons on a dart board. It's very dark, and it sure doesn't "show us all a way forward. . ."
No, I don't know what portion of the audience gets all this. But it's a total send-up of our culture. It's a format that goes all the way back to the Greeks. Like the current "Brandon" presidency, it's a farce.
