What's the most understated movie you know?

When I say understated, I mean stuff such as lingering shots, glacially slow pacing, minimalistic dialogue, letting cinematography, editing and symbolism do most of the story telling, minimalistic cast, lots of quiet moments, little to no action, either very grounded or very abstract and so on. I guess Tarkovsky movies would be included based on what I've been hearing about them, but I'm not sure which one to begin with.
