I really loved S1, with how the story line was woven together and how all the characters were portrayed, not to mention Jung So Min's acting and Lee Jae Wook and her chemistry. When I began S2, I was a bit disappointed that Jung So Min wouldn't be in this season. Don't get me wrong, Go Yoon Jung was really good but apart from the story being extremely rushed in season 2, I found that the onscreen chemistry between the two didn't match that of Jae Wook and So Min's. I couldn't bring myself to accept the fact that Jang Uk could fall in love with someone else so easily. I know it had been 3 years and that's more than enough time to get over someone however even in season 2, he was angered by Bu Yeon when she recollected Naksu's memories and then him falling for her was very sudden. I found it a bit frustrating that Naksu's character was hardly portrayed and it felt like Bu Yeon, although having Naksu's soul, was a completely different person all together. To be honest I expected Naksu and Jang Uk to retrieve their powers (and not die obviously) and fight side by side together in season 2 so I was a bit disappointed about how things unfolded. Although the writers could have done much better with script of the 30 episodes that were aired, it was a decent show. Even though I wouldn't rewatch the show, it should be watched by everyone.....at least the first season.
