I've read a few things about how disappointing Moon Lover's has turned out to be for some viewers. In fact that's why it took me a little to make up my mind and give it a try. But I think I can't see their point. Bearing in mind the high standard production values it displays, the overall result is a little underwhelming. The biggest problem with the series is that it was too ambitious. I think I already said it in another review: that's the main problem with most dramas these days. Since the target audience is expanding every year, the pressure is bigger. Also, most idols seem to be forced to develop good acting skills in a short span, even if they've hardly had any training. There were high expectations on the cast in this one. The result was just OK, I think. I have to say, however, that I don't agree with all the criticism that IU's acting had to face. I actually really liked her performance (I have to say that I haven't seen any of her previous works), even though it's true that her character was poorly written. In my own humble opinion, the best developed characters were the ones played by Kang Ha Neul and Kang Ha Na. And their performances were good enough. I really REALLY liked Woo He Jin's moving performance and her character's relation with IU's. As for Lee Joon Gi... well, he'll be a favourite of mine always and forever, and this character suited him. But I insist: I miss him in more lighthearted roles such as the ones he played in Iljimae or Arang. I really miss this goofy side of him. He seems to be obsessed in proving his value in dramatic roles. All in all, I liked the story and its message (I haven't seen the original Taiwanese drama), but the direction was lacking. I feel that's also a big problem in many dramas: they have a good primal source, but some directors don't seem to know what to do with it. They wanted to try innovative things, like leaps in time (some of them I felt that really worked), but as I said, the excess of ambition was a setback. I liked the close-ups, though. Some people complained about the overuse of close-ups, but I actually liked them (and any Lee Joon Gi, Kang Ha Neul or Nam Joo Hyuk close-up is always welcome and appreciated, let's be honest). Anyway, in spite of its flaws, I don't think you're going to regret watching this drama.
