Nice start, caught my attention in the first couple episodes, after a while it got boring though, And as per usual in my case, it was a pain to sit through. The last 2 episodes were good however I felt that a certain section including Lee Rang that came after a major event in the show was a little rushed. And then the very, very ending. It was a nice detail but like explaination please? ( I guess its a little open and up to own interpertation unless i missed sum) Honestly I liked sin jus couple more than the main. Lee rang's development was nice and their brother relationship was nice to watch.
