This is not a movie for everyone. The characters are flawed and that's what makes them real. We do certain things in life without any reason. And that's what happens in this movie and that's what people are criticising but it is also that thing that made me like this movie. Not all characters are free of fault and the ones who look like the victims are equally to be blamed for everything that happened in the movie. I haven't read the novel but the movie is making me want to pick it up.
Anders(played by the brilliant Ben Mendelsohn) has taken an early retirement but decorating his house and sleeping with strangers is not bringing him the happiness he expected to find after cutting ties with his old life. Even if you can't relate to his story, you'll be able to relate to him.
I know Netflix has been failing in the action and romantic movie genres but in my opinion, they're not doing so bad in drama movies.
