Twins swap places in a story about survival and finding one’s direction. Solid performances all around. Shot conventionally but nicely edited. Simple plot but the characters, relationships and themes make it more complex than it appears.

Solid production but the plot is uneventful. Autopilot pacing. Relies on performance to carry the series.

Intriguing premise. Exposition/revelation-driven so the structure is a little crude but pacing is well-managed enough. Solid series.

Plot follows nurse working in the psychiatric ward. Good balance in tone. Good performances. Some structural clumsiness but a decent series.

Lacks plot. Themes are apparent but under-developed. Mostly looks good. Relies too much on Park Bo-young and Seo In-guk to carry the show.

Mostly enjoyable romantic dramady and very funny at times, but the plotting and pacing plateau in the second half of the series.
