Honestly felt more like a kpop fangirls wet dream rather than an historical coming of age drama. Which is a pity, because the actors did really well, but the writing was horrible. I honestly don't know what the writers were thinking because the characters were interesting, but not developed enough to be interesting or matter and the acting wasn't that bad, Go-Ara is a brilliant actress but her character was written so badly she couldn't show her skills. Park Seo-Joon did a brilliant job with what he was given, although he wasn't as badly written. The worst character was by far Han-sung. His character was so interesting - A fun-loving young man who loved his peasant brother dearly, opposed his families views, and had the burden of being the sole heir. THE POTENTIAL FOR DEVELOPMENT WAS IMMENSE. But he got no development and was shown perhaps once every other episode. He was a big part of the shift in direction towards the end but his dynamic with various characters wasn't explored so it was more of a fact stated than actors showing this - again, writers fault, not the actors. Some characters had interesting histories but weren't explored at all - mainly the Hwarang who didn't know who his father was. The romance was just thrown in their for the sake of showing some kissing. Park Seo-Joon and Go-Ara did well enough to show that their characters cared for each other, but story wise, the romance wasn't needed. I cared much more for the dynamic between Hyung-Sik and Seo-Joon. The plot had potential, but showrunners focused more on Go-Ara walking around depressed than moving the plot forward. Overall, the acting wasn't bad at all but the showrunners left no room for the actors to, well, act. The characters were so 2D that it was like asking an actor to act as a lifeless corpse.
