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

Moderately intriguing. Pacing can be better but no big deal. Nicely edited. Amusing score. Go Min-si is flipping nuts. But in a good way.

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