Sky Castle is a well-written and well-executed drama. In other words, the cast and crew did an exceptional job of portraying the meaning behind the story. It's not your typical Korean drama out there. It tackled on the issue of the educational system in Korea but it also gave light to the importance of families and self-exploration. There were a lot of characters to follow but each individual story was depicted very well-- everything made sense and wasn't forcely connected.

I felt for each individual character. For instance; at first I thought I'd hate Kang Ye seo, Han Seo Jin, Kim Joo Yeong and Professor Cha; but in the end I grew to understand their characters more. It's definitely unusual for antagonist characters to be understood but their stories were portrayed very well.

This is the Korean drama that is worth watching.
A Korean drama that you'll definitely learn from.

It deserves such great ratings. Korea has spoken, you should watch it now.
