Serious crack-tastic drama. It gave me heartache and happiness, twisting my heart into a knot, in good ways and bad in every episode. The best part about Master's Sun is definitely the chemistry everyone's talking about between the leads, Gong Hyo Jin and So Ji Sub. It gave me so many tingly feels. The ghost story per episode didn't feel too filler to me personally. I enjoyed most of them since they were ways for the romance to develop. Some even had an emotional impact, others left a bit to be desired. There were quite a few flaws regarding the 'rules' about ghosts and their abilities, and the drama did confuse me at times because they weren't consistent. Let me ignore those flaws though! I purposely ignored those flaws and just accepted all the supernatural aspects of the drama as they were shown, which made my drama experience much better. I guess I also have to mention the rich boy, poor girl thing. Yes, you can say that the plot- on the shallowest level- is about that cliche but I think the drama builds off it with many layers. Though I enjoyed the skinship from the very beginning, they didn't have an effect on me until a few episodes in since there wasn't enough emotional attachment. But when it finally hit me, bam! Wow, I became seriously invested. I love their relationship development so much. Whoops, did I say that already? I enjoyed seeing Joong Won's change as a person and how his sun, Gong Shil, continued to change him, bit by bit. His trust in her just kept growing and that was a pleasure to watch. Their relationship is the anchor of this drama. Without the strength and brightness of it, the drama would've fell apart. I think if the main leads weren't Gong Hyo Jin and So Ji Sub, I wouldn't love this drama that much. They brought their characters to life and made them seem so realistic. Gong Hyo Jin, as usual, was amazingly touching. Her emotional depth through her character, Tae Gong Shil, sparked in each and every scene. I liked the second leads. No vindictive second leads! It's always great when the second leads add fun scenes to the drama, and not detract from the drama. I really liked Secretary Kim; he was like the cupid representative of the viewers. Lets talk about one of the main plot points: Joong Won's tragic past. Was that done well? I'm not sure to be honest. It was amped up for most of the drama, only to be hastily resolved in one episode. From the halfway point, though, I already began to disregard the plot lines and just try to go along with the story. After all, just focusing on their chemistry was must more enjoyable than trying to analyze patchy plot points. The extension? Personally, I hated it at first because I thought Gong Shil's actions were off par with her character based on previous episodes. In retrospect, I guess I could understand why she did why she did so I can't call it noble idiocy. Nevertheless, I could've done without it, so episodes 13-16 felt like some unnecessary angst. The finale episode was done well though since it was extended, it wasn't rushed. I did like the metaphors integrated throughout the drama. In a way, they helped justify some of the Hong Sister's writing decisions, in my opinion. The metaphors also gave depth to the plot and also the the relationships. Overall, the drama came full circle at the end, so it wrapped up nicely. The OST is amazing. Every song is perfect. Some songs are hauntingly chilling, others are emotionally touching. I even love the instrumental music, which isn't that often! Every song seamlessly fit in with the scenes. I already started re-watching some scenes. I will definitely re-watch this. I recommend this for those who love romance like I do, and also isn't a stickler for supernatural 'rules' and how the supernatural world should and should not be. In the end, take don't Master's Sun's plot too seriously and you'll come to love what this drama offers. (9.5,8.5)
