Unfortunately, I've watched all the episodes, while this entire drama should have been stopped at the episode 34, after which nothing makes sense, and my ratings refer only to that point. And until that point, the investment made by the creators was such to make a very picky (I usually drop 99% of shows of any production or country) and have-no-time person (as myself) to spend her time watching it with great expectations, all deluded by the last 6 eps.

The creators made a huge effort to build up credible characters within a credible story. The Italian saying for fiction: se non è vero, è ben trovato (if it is not true, it's (still) nicely figured out", usually used for the works of fiction) had its application. Further, a huge attention of creators was made to make sense: plots, subplots, all human relations made sense, characters were well explained, had sufficient screentime and particular personal growths that allowed us (the audience) to care properly about each and every of them. And after all that construction effort, what happened next was a complete disaster.

In the last 6 episodes the creators decided to massacre everybody and destroy every sense in the story they've built up so nicely. As in Italian saying, "everything was figured out nicely". Holly crap, can someone tell me what's the purpose of such a thing? To tell us "wars are sensless"? Well, we know that without investing so much time and feelings. Or to tell "all men must die"? We know that, too. But such a huge sacrifice happened without principle of justice being properly served. Ending such a great story with CY's dream of unprobable "10 years after" not only doesn't render justice to its protagonists (btw, some of them dissappeared without trace, minister Du, where are you?), but makes their (and our emotional) sacrifice senseless, too.
Or the message was "there's no tomorrow"? Indeed, there's no tomorrow expecting our heroes' & heroines' next move. Hello, authors, what was your final message? From the original Chinese poetry, I deduce Guanshan is a place or time or circumstance where a person can reflect on their "wordly" attachments and loyalties. The Chinese title did not serve the purpose, while the English title is missed, too, ie., it served untill the episode 34 - after that episode nothing makes sense.

Special "Guanshan thoughts" for the scriptwriter:
1) It's impossible to move such a huge military forces in a presided area without being noticed.
2) you did fine with LTG's Oedipus complex, but once they drop it, no way any marriage or relapse will occur.
3) what kind of message you've exactly wanted to launch?
