沉重與飽含悲傷的故事，詩意與充滿哲思的旁白。

故事很悲傷，發生在東歐劇變下的蘇聯。兩個深愛孩子卻在其他方面迥然不同的父親被命運牽連在了一起，凸顯了小人物被時代洪流裹挾的無奈。電影最突出的是男主沙啞的畫外音旁白，從IMBD摘錄了這部電影的兩段旁白。

第一段編劇用物理學上光的波粒二象性來類比闡述女人和孩子的比喻非常精妙並充滿美感。前幾天剛好看到一條部落格，說物理學歷史上如何從牛頓認為光是一種粒子，到後來惠更斯提出光的波動說，再到愛因斯坦統一了光的波粒二象性。陡然發現科學和文字可以如此美好的結合。

[voiceover] Light is a particle and a wave. This is hard to understand how a thing can be two things at once; but a woman is also both a particle and a wave. She's a wave when you see her reach down to pull a shell from the sea, and you feel her beauty pass through you like electrical current. She's a particle when her hair brushes your face, and her hands push into yours. And a child is also a particle and a wave. He is a wave the sound of his pain shoots through and twists you away from yourself. And he is a particle when a doctor hands you a baby; a small mirror. Women, children and light can be two things at once; a particle, a wave. They ricochet off the hard surfaces and illuminate the corners. Without them it would be far darker.

第二段編劇把我們每個人的人生和來自宇宙深處的放射性元素的半衰期做了類比，我們都會隨著年齡衰退，亦如那些宇宙中最閃亮的星星，它們都會最終失去最初的明亮，變成陰冷的鉛元素。而我們則一步步衰變為一段段或明或暗的記憶。

[voiceover] Uranium, Neptunium, Plutonium. They came from space; found their way here by comet and meteorite. No child ever wished this from a star. Hiroshima, Nagasaki, Chernobyl. Problems with half-lives forty-thousand years long. Half a life. Time takes half of us away and comes back later for the rest. We are children and then we are parents. We are long division. Slowly we decay into memory.

 [voiceover] In the end, everything decays to lead, number eighty-two on the periodic table. All of the brilliant things born in the center of stars will have turned cold and gray. Everything is moving in that direction. Toward lead. Impossible to stop.   舉報
