I haven't seen the original, so will review it solely for this one.
It was an amazing show, the lead cast played their characters brilliantly, the chemistry between the two main leads was fabulous and probably was one of the reasons the show is good, as it makes you believe that yes the power of love can create magical things, goes beyond time.
It was an easy 9star , but the ending was rushed for me. Usually in kdramas they really stretch it out even when the plot doesn't demand it, but here it was very much needed and Netflix rushed things in the end, a more romantic, fulfilling end was needed for the main leads, but it just feels rushed and left me with a sense of incompleteness.
The music is good, all 12 episodes are beautifully shot, the script is tight amd there are no lags, no drags whatsoever.
A must watch show. Though I wouldnt recommemd it to those who haven't watched a kdrama yet and this will there first.
