The series, drama, plots and subplots are outstanding up to episode 50. Afterwards it goes down hill down to the apparent suicide of the main character which is completely off character for being the Ultimate Scholar she would have come up with a plan like the one I have read about in the novels translation.
The series is worth watching by the settings and clothing alone but is quite weird that Ning Yi's obsession with silk is downplayed as well as the quality of their plans at some point as well as most characters by the end it feels extremely rushed or PowerPoint Dune feeling like. The chemistry between the characters is great and there is more romance in there than in any Hollywood Romance flicks which makes the ending inconsistent.
