Film noir expects us to believe in the existence of mysterious bags of money and the people who think they can breezily steal them. You can't approach film noir with a magnifying glass of pristine logic. Noir is about incontrollable human impulses, usually of the worst kind. If you surrender yourself to the pleasures of the genre, you are going to have a great time with this film. It dots its i's and crosses it's t's pretty cleanly. Unlike other movies of the genre, that become harder to believe as they progress, this one sets up the plot very cleverly and creates very clear and believable motivation arcs for the characters, even though as with any noir, characters are not there to be a mirror into human psychology, (except of the most basic kind: lust, greed, fear and revenge). They're there to zip the intricate plot along. The Square is a very enjoyable puzzle that bears more scrutiny than other films of its genre but not too much. If you think about it too hard, it can become preposterous, but it's still oodles of fun.
The film is preceded by a fabulous short film by the same director. A stunning little jewel of very dark comedy.
