Throughout the film, Aronofsky explores themes of isolation, loneliness, and the complexities of human relationships. The movie is a metaphor for the destructive nature of human behavior, with the house serving as a symbol of the couple's fragile relationship.
The movie follows the story of a young poet, known only as "Him" (played by Javier Bardem), who lives with his wife, "Mother" (played by Jennifer Lawrence), in a beautiful, isolated house. Their peaceful life is disrupted when a stranger, Man (played by Ed Harris), and his wife, Woman (played by Michelle Pfeiffer), arrive at their doorstep. As the story unfolds, the couple's lives are turned upside down, and they become embroiled in a series of disturbing events.
As for the Vietnamese subtitles, it's possible that a version of the movie with Vietnamese subtitles was released in Vietnam or other countries with Vietnamese-speaking audiences. However, I couldn't find any specific information on a version titled "Mother 2017 Vietsub Exclusive". It's likely that this is a fan-made or unofficial subtitle track, which may not be widely available or officially recognized.
