La Collectionneuse. One of Éric Rohmer’s Six Moral Tales. Like Roman Holiday, this one centers on a question that doesn’t get answered until the last minute. It wasn’t as much pure fun, but I still respect a patient movie. From Phillip Lopate’s Criterion essay:
Here we see one of Rohmer’s most original tropes: the tepid attraction. It flies in the face of all cinematic convention, which dictates that the encounter of a good-looking man and a good-looking woman must lead to grand narrative passion. […] Rohmer views the problems of indolent, potential-laden, prolonged youth in this film from the perspective of the middle-aged artist, who knows that the clock is ticking.
