This is a beautiful, captivating and heartmelting drama! One of the best drama with the most visually stunning location and actors and actresses! It has grandeur in its own and will become one of those classic drama that will last in our memory and heart. Most of the adaptation I have watched, oftenly are a let down to me. But this is an exception,and I would say this has been one of the the best adaptation if not the BEST adaptation of any drama that I have watched. I am a big fan of the original chinese version. I have scored the cdrama a perfect 10 and I will do the same with this korean version. The story for me is perfect given that it has resemblance with history. The plot is engaging together with the characters. The writing has flaws but they are covered by great cinematography, costumes and acting. The setting is visually stunning! The pacing is just right given that it is historical in nature. I enjoyed watching how the plot are interspersed with each episodes. I think 20 episodes is enough to create a beautiful story of love, friendship and family ties! Characterization is well written including the progression of the loveline! But what amazing in this drama are the actors, all of them acted brilliantly. I am surprised that IU has improved a lot especially towards the end of the drama. Two thumbs up to her and to all the prince (s). Music is excellently chosen, they all stir the emotions and give more gravity to a scene. Yes I am gonna rewatch but only for those light and feel good scenes and not those that rendered me heart-broken. This is highly recommended drama, many layered of emotions, lots of twisted plots, great acting and grand visuals!
