In full disclosure, I'm a Bai Lu fan, have been for years, OF COURSE I was going to watch this show no matter what.
Also, I actually think Bai Lu has good chemistry with most other ML she has worked with, but her together with LYX is near or at the top of the spectrum.

Story - Docked a point here, because as much as I loved this drama, if I'm being a bit picky, I still felt the final arc was a bit rushed and some things left a bit TOO open or w/o closure. Not just with the main couple, but some side characters as well. I have read (ok, skimmed) the original webnovel as well. They are different enough that the stories shouldn't be compared, but I would say the webnovel had a bit more explanation and closure at the end at least. Wish they had made this longer, given it more episodes, even if it would require 2 seasons, and taken their time with the storytelling.

Acting/Cast - its Bai Lu, I'm giving a 10. But in seriousness, the acting carried this drama for me. And despite me picking this drama up for Bai Lu (who was amazing as always, and beautiful of course), you really have to appreciate how well Luo Yunxi did, portraying not just multiple characters, but also the complexity of Tantai Jin's personality and his growth as the story progressed. This role was a tall order and LYX delivered it beautifully. The supporting characters also did their parts well. I might've found the Xiao Lin/Ye Bingchang couple a bit bland but I think it was how they were in the story itself and not an acting issue. CDL did a fantastic job portraying the two-faced little b*tch of a sister, and as much as I wanted to slap her (a sign of a successful villain), she still was able to somehow convey a sense of her motivations/reasons for turning out the way she did. Bai Lu's character Li Susu does not go through AS drastic of a change as Tantai Jin through the story but you can still clearly see her gradual transformation from a more naive girl with this world-saving mission who doesn't yet fully understand all that this mission would entail to someone who has had to make tough decisions, who has sacrificed, who bears the weight of heavy responsibility, who has felt guilt, who has been tricked and deceived, who has had her heart broken--and all the while her unwavering determination to protect the world.

Music - Love LYN's voice. I screeched when I heard the opening theme. Other songs are beautiful too--evokes alot of emotion. Especially when they play certain themes at certain key points. It always reminds of those scenes when i hear the song.

Rewatch - If I DO rewatch, certain parts at least. Lets be honest, there's a whole lot of misunderstandings and a whole lot of angst. I might skip over the REALLY painful parts if I'm rewatching.

Nitpicks - So much blood. Some parts I really wish they didn't vomit blood or toned it down to a small trickle rather than a big mouthful. Makeup was sometimes a bit heavy, especially on Tantai Jin. He looked great but its just very apparent he has a helluva lot more makeup on than the people around him. Besides Tantai Jin, there was a scene where Ye Qingyu gets into a fight with Tantai Jin where Tantai Jin refuses to leave his dead wife's side--I was shocked with his makeup there--but at least the actors knew and poked fun at it too (Ye Qingyu's actor joked he looked more like a corpse than Ye Xiwu who was actually supposed to be a corpse).

Overall - Love the drama, love the actors, love the music, loved the details in the beautiful costumes (although c'mon whats up with the devil world wedding outfits...i know its devil world and costumes are used to portray the state of character/plot to a degree, but can't they have prettier clothes that don't make me want to wish them Happy Halloween). Just be prepared for alot of angst and pain so if you're not ready for something that isn't all light and sweet and fluffy, table it for until you're ready.
