As an evocation of a first love during a summer vacation, the film is perfect: vignettes take precedent over plot. As for the romance itself, well, it’s not very romantic and surprisingly chaste, and wouldn’t make too many blush.
Michael Stuhlbarg’s monologue at the end is great (as is Chalamet’s final scene, up there with the ending of Tsai Ming-Liang’s “Vive l’amour” for embracing heartbreak.) But, as Ian McDonald once pointed out about Sgt. Pepper’s, the album would just be good-not-great if it wasn’t for “A Day in the Life,” and Stuhlbarg’s speech is just that. The film rests on those moments, and without it…well, your mileage may vary.
