Well structured, simple jealousy and betray driven story, seasoned with supernatural elements.

Wishing Stairs tells a story of two best friends, Jin Sung and So Hee, and the rivalry born between them because of the upcoming competition. The movie effectively made me question if the events presented to me have any supernatural origin or are the result of the feelings of guilt in Jin Sung and obsession Hye ju displayed towards So Hee. Sadly, the director and writer straightforwardly answered said question by the end of the movie, instead of leaving me, as a viewer, with the possibility of self interpretation.

The structure of the story is simple and extremely easy to follow. The linear storytelling without countless flashbacks to the past events makes it a good, digestible horror flick that does not require much brain power to understand.

The performance from the main cast and the production value were truly good. The director knew the limits of what she could achieve in that time, and did not overuse cheap and not well made CGI or special effects for jump scares.

Overall, I would recommend it if someone wants to watch a fun, simple story that answers all the questions and truly guides you through the plot and events happening.
