Again, this is one of the shows where the reviews were so positive that I was surprised to have a different opinion. (In most cases, my impression of a show is the same as the majority's, so I don't post, but in cases where I have a markedly different take, such as this one, I figure that a different viewpoint might be useful).
The overall story is not all that unusual -- very much like Three Lives Three Worlds in that the characters encounter each other in distinctly different situations, and that the general story is a love story. However, the difference is that this show seems to have main characters that are so irredeemably selfish that they actually seem no better than the villains.
SPOILERS AHEAD
Every trauma experienced by the main characters was brought on by themselves. Where in other shows, people are foolish enough to hide information that when unexpectedly revealed, produces great harm, in this show, they're hiding information that they plan to reveal anyway, so they cause great harm and they KNOW that they will cause great harm but do it anyway.
Tian Qi was willing to sacrifice all of the worlds to save one person, and we're supposed to feel sorry for him for being villified? (Not to mention, if all the worlds are destroyed, the person he wanted to save would have been destroyed too, so exactly how was he helping?) Hou Chi made thousands if not millions of people vulnerable to harm for the chance to help a single person, and we're supposed to feel sorry for her when she's punished or when her love disappears? Everyone knew the evil in Wu Huan but did nothing to stop her at the earliest stages when she could have been stopped, allowing her to go on killing sprees for centuries.
Bai Jue/Qing Mu could have spent a happy year (perhaps more) with Shang Gu/Ho Chi had he just been honest with her. Instead, he chooses to hide information from her and then disclose it after his death, ensuring that she feels maximum pain while he's alive (from his shunning) and after his death (by knowing that he was making a sacrifice for her). Being apart served no purpose. It made Shang Gu/Ho Chi no more safe, nor did it help him to defeat the villain. It seemed to do nothing other than to dramatize the pain she felt when he eventually revealed the truth.
All of the "heroes" of the show seem to be enormously self-serving and the drama manufactured, which killed off any charm that the show otherwise would have had.
