Reviews are subjective but honestly I’ve never rewatched any drama as many times as this one while it was still airing… not even my beloved CLOY. For me, it’s perfect: the script, directing, camera work, the length, the tempo, no unnecessary or cringe scenes, and so many details are well thought out. The OST as well, and best of all, the acting and the chemistry between the main leads. We see a rarely seen nowadays top class acting from not only main leads but also supporting actors.
Of course it has a few parts in the form of illogical and slightly realistic consequences of various accidents, but this is a common technique in this genre and is no more miserable than in other dramas, and it does not affect the story or the pleasure of watching.
To be fair, I haven’t seen a lot of the iconic and older dramas yet, but I think I’ve watched over a hundred various dramas already, and this one has everything I expect from a kdrama. For me, it’s in my top 3 and I will rewatch it more than any other series for sure.
