Then I saw the movie. It was weird. From the very beginning there were some obvious inadequacies in the editing and the acting. This might be taken as something charming, something unpolished on purpose, may be a stylistic decision. At times the movie feels like a movie from the 40s (the scenes from the birthday party and just afterwards with John Malkovich); at other times it nods to Woody Allen. But what makes it hard to watch it in isolation from the current events, is the fact that the movie is so much in a dialog with them. Mindfuckingly so. It examines the grey areas when it comes to consent, signals people give in the flirting game, what is objectively appropriate (if there is such a thing) and what is acceptable from society. The latter is as divided as its members.
As for Louis CK's acting, the confused expression worked better in the context of the series Louis, but it could hardly carry a whole movie.
Overall, it is an interesting film to watch. I am still a fan and a supporter and wish to have the opportunity to review many future Louis CK's projects.
