Though many of us were complaining about the cast, but I'd say if we don't keep in mind that it is the sequel of The Night Of The Comet 1 , then you would actually be ab;e to enjoy the show.

Basically the only similarities in both show were as follows:
1.Male leads were rich and female lead belonged to middle class family.
2. Male leads time traveled because of the comet.
Just these 2 were the similarities , Else it was really really different from the previous story.

It was a full entertainment drama. Casting, Story and Production was really really good.
I won't write much cause then I will actually spoil all the suspense. I would say you should give it a try.
Good Luck!!!!
