Beautiful, sensuous, atmospheric, devastating tear-jerker. The ending hit me like a ton of bricks. I wasn't expecting that. Justin Chon (writer, director, lead role) is just fantastic. Alicia Vikander, Linh Dan Pham and supporting cast also very good.
The point that the film makes is hammered home heavily. You can't possibly miss it. A brief coda highlights some real-life examples.
Also, at times, I thought the musical score was a bit heavy-handed.
The soundtrack, just released on Spotify, has 47 tracks(!), but the one track that I wanted to find wasn't included. After some digging, I found it: "In Fantasia", by Kishi Bashi. It is used in the trailer and in the film.
