Outstanding drama with superb acting from the entire cast and great cinematography. The couples in an exclusive gated housing complex (Sky Castle) have ambitions for their children's education to make them the best whatever the cost. It is apparently a reflection of how some Korean parents put so much onus on their Children's ability to excel in their chosen career path (hopefully exaggerated) The various families all have differing ideas of what a parents role is and the acting certainly makes you believe they are real families. Suicide, conflict and murder will eventually make people appraise what is important in their life's.
