It's been years since I watched a drama with such high quality. It delivered everything, from comedy thriller angest friendship etc...
Sky castle was for me a masterpiece because it made the viewers want more of it, expect more of it. It makes you stop and think about each and every scene. Memorize the dialogue and even put yourself in the characters' shoes.
There were never a 100% black or white character. Pure evil and pure good. All the characters are gray, you can choose a favorite and root for them but it doesn't mean that your choice was the default for someone else.
There were a lot of mixed opinions about the final ep but honestly speaking, as unrealistically some points of it were I was glad that the drama ended that way. In the end nothing is perfect, even Sky Castle.
As I rewatched many scenes while waiting for the next eps every week I am sure that I'll end up rewatching this drama a lot.
And as each episode ends with it of course I can't end this review without dropping the iconic "We all lie~"

HIGHLY RECOMMENDED!!!
