The bad sides:
As a person who does not like killing people or torturing them no matter what they have done and is against the death sentence - because I believe people are not born evil they are mostly raised in an environment to become one, and we can always at least try to help them if possible and even if we were not able to we are not gods to order a death sentence ( well the irony is that they were gods, haha), I really didn't like the parts having this concept and I would be much more satisfied if they removed especially the first half of episode 55, that was such a pain to watch. And god, the way good and evil are portrayed in such stories, there is no one like that on earth or heaven :D
CGI was not that bad but there were some obvious errors that it was hard not to notice.
One of the strange things in the story was that sometimes they could save someone very easily and sometimes they couldn't. And who on earth would sleep with their hairpins still on? maybe in heaven? :D

The good sides:
I liked the drama overall if the parts I mentioned above are ignored but to be honest I was more invested in the side love stories and not the main couple. Their love, I couldn't feel it for the most part and they were so mean sometimes I could not bear it. I loved Lian Song and Cheng Yu relationship they were so interesting to watch and I wish they had more screen time.

the acting was satisfying. I think Bambi Zhu is a really good actor as I could feel her pain and misery.
At first, I wanted to drop it but I gave it a second chance and it turned out that the second half was much better. There was not much boredom with this drama in my opinion and it was a good watch.
I don't really rewatch any dramas but there are some scenes with Dong Hua and Feng Jiu that I rewatched a few times that were very emotional.
