Pros:
1. Story: It was very compelling. There were a lot of unexpected twists and turns that kept me hooked on the series.
2. Music: The music heightened certain emotions (conflict, longing love, etc.) very well.
3. Visual Effects: The flashbacks and blackouts heightened the amount of drama and were well utilized.
Con:
1. Characters: The characters were very one-dimensional and the interactions between some of them seemed to be very similar throughout most of the episodes, which made the series feel rather long. I also felt that the cat, while very very cute, did not add much to the story.
