I understand that this film is intended to be artistic. The storyline and how the characters develop seem unimportant, maybe even disregarded entirely. What the movie delivers are visual moments, emotional recollections that shift between a sense of longing and a touch of discomfort. I feel it attempts too much, ultimately failing to engage the audience, seemingly content with the idea that those who don't appreciate it simply aren’t perceptive enough. Take, for instance, the camera pausing on an empty space—like a staircase—for anywhere from fifteen to thirty seconds after someone has already left. What purpose does this serve in enhancing the film’s emotional resonance? And how meaningful is it to watch a boy gaze into nothingness for a period of time without any insight into his thoughts or emotions? Shouldn't we be invested? Also, is it skillful filmmaking to have characters speak so quietly that you strain to hear them, only to then be startled by the frequent and jarringly loud musical cues? By all means, strive for artistry, atmosphere, and a sense of nostalgia. But if you’re going to include narration occasionally describing what's on screen, it would have been simple to weave in some storytelling as well. It seems like pleasing both those who enjoy fanciful visions and critics—as well as people like me with less refined tastes—wouldn’t have required much extra effort.
