I'll be brief.

Wasn't going to review this but doing it in response to some other reviews that I totally disagree with.
1) Agree this is not a rom com. But it is not a tragedy either (for those of you who hate crying bitterly at the end, like me, don't worry, you won't.)
2) I didn't watch the Manga beforehand, and so I will take others' word for it that f you read it you'll be disappointed in this version.
3) saw that a reviewer wrote that Shin se kyung can't act. This floors me. I think she's one of the most amazing Korean actors I've ever seen. (See Run On.) The woman kills it in every roll! Her silliness is beautiful. But more importantly, she can express raw heartbreak better than almost anyone I've seen. as well as holding emotion in and it dripping off her eyelashes.
4) agree the ost is gorgeous.
5) Had no problem with ML coming off as arrogant and narcissistic. He's a god.
6) Agree that it's slow. But I've seen far worse.
7) 2ML actor is wonderful.
8) no opinion as to whether ML actor would have been better played by someone else. I think they had chemistry. He acts cold and distant, and at first acts like the FL/"god servant" is beneath him, and falls despite his will power.
9) Agree that some aspects were slow to take shape, and agree wholeheartedly that they should have had more scenes of the god world. That was a disappointment.
