Parasite
Had to watch for film class. I absolutely adore how this movie makes you ascends and descends to both the upper and lower classes. The lower houses are so claustrophobic and crowded, but you ascend in the social hierarchy it feels more free, open, and lively. Literally green everywhere. The camerawork amplifies these feelings too.
The pacing is also terrific. The twist and climax never get old. This is truly an endlessly re-watchable film.
