Angel's Egg

Angel's Egg (Tenshi no Tamago) is a 1985 Japanese anime film directed by Mamoru Oshii. The 2 characters are a girl and a young man. The girl is protecting a large egg in an abandoned decaying city, and the young man finds her and stays with her. She keeps asking him who he is, but he never responds. There's very little dialog.

It looks like a triumph of metaphor and symbolism without sacrificing plot. But then I think 2001: A Space Odyssey is a great film, while the rest of The Family considers it a triumph of trippy visuals at the expense of plot. Angel's Egg is pretty to watch and to listen to (the music is by Yoshihiro Kanno) if nothing else, but there is much more here.

Nihon Review closes with this:

Ultimately, I find it hard to not recommend Angel’s Egg to the more seasoned anime viewer since the movie is undeniably immersive and shows what can be done with the animated medium. Just be warned that if you cannot enjoy an anime purely for its aesthetics, the movie will probably bore you out of your mind.

Japan Cinema says,

For one of the first times since I began watching anime I think they managed to get some Christian references correct or at least in a recognizable order. References to the birth, re-birth, temptation, ascension are all present. One of the few anime Directors who has been nominated for both a Palme d’Or and Golden Lion, Oshii is famous for his philosophical rhapsodies displayed in his anime

Anime Dream says, "As a whole, Tenshi no Tamago is a rather memorable gem of existentialism, something I cannot recommend enough if you are interested in this theme." Rotten Tomatoes has an aggregate audience score of 85%.

I watched this as part of the Once Upon a Time Challenge Quest on Screen.
