The greatness of this drama is in its main characters. They are mature, thinking people with none of the usual simpering of the ganre. They are all complex and rounded and aren't so easily put into the usual boxes of good or bad.
The music and costumes were good, but as usual the white skin filtering was too much. Wish the Chinese industry would stop with this nonsense, since they already have such good looking actors without the filters.
The downside of the drama was the number of episodes. Forty episodes were too much for the story and the last five episodes I was mostly skipping and skimming. It was a good drama but it could have been excellent if it was shorter.
