Luis_989’s review published on Letterboxd:
Fantasy of the Girls turned out to be a much more practical and straightforward story than I initially expected, which was both good and bad.
This is considering that its narrative involving lesbianism is not a narrative often explored in South Korean cinema and for that same reason can go either way.
However, it works to a certain extent because, although most of its events are anodyne, the film does not opt to go down a crude or melodramatic path that would've been more than predictable, and therefore helps the story to be more interesting and not become tiresome, but there's also an obvious but understandable lack of depth.
I didn't think much of it, but I can't say I disliked it either.
