The main reason I liked this drama was the plot, unpredictable and captivating, it does not allow you to get distracted not even for a second or you will miss the change of setting and time.
The production is incredible, honestly one of the best I've ever seen. The choice of places, the direction of photography and cinematography was extremely high-quality, the music is perfectly matched with the setting, and whenever I listen to "Recuerdos de la Alhambra" on my own I shiver remembering the scenes in which this song was used, I remember the feelings, the characters, the landscapes and the infamous train scene and the sudden rain.
The actors were amazing, I loved the romance between the two main leads, even though it was a little predictable (maybe the only predictable detail about the plot).
Not gonna spoil the end, but it made me cry. I still think about it nowadays (I finished it in February), and it still makes me shed a tear.
Really a great drama overall, one of the best I've ever seen!
