Lost in Starlight combines a promising romantic premise with a futuristic Seoul and a distinctive animated style. Nan-young dreams of becoming an astronaut. Jay has stepped back from music and works among analogue audio equipment. Their relationship grows in the space between thwarted ambitions and a desire for something real.
The contrast between digital surroundings and records, tapes and older machines is appealing. Music and quiet conversations let the romance develop without rushing it. The prospect of a Mars mission then raises the conflict between a lifelong dream and a relationship rooted on Earth.
The images are exceptional. Detailed animation, cold neon and nostalgic warmth create a city that feels futuristic without becoming impersonal. The light and colour give the film an atmosphere well beyond the usual streaming look.
Music is equally important, helping scenes move and deepening their melancholy and hope. It is part of the storytelling rather than an accessory attached to Jay's occupation.
The dramatic structure is less satisfying. The middle slows, developments are predictable, and the conflicts between intimacy and ambition do not acquire all the depth they might. Nan-young can feel underdeveloped, while Jay sometimes functions more as a symbol than a person.
I give it 3 out of 5 stars. The film has feeling and a recognisable style, even if it does not fulfil every promise of its premise. Viewers wanting a romance that looks and sounds different should find plenty to appreciate.
