I like the Korean version much better. The original is also better then what I have seen of the Taiwanese version so far. Jang Geun Suk did the best job and also Park Shin Hye. But this version is good.
So far I'm not impressed with this version. I'm not feeling Jiro as HTQ at all which saddens me because I usually like his acting. The lead girl is ok, for her first drama. I like Deok and think he is doing a good job. I watched the Japanese version and liked it, but I feel the original Korean version is the best. I have watched it 3 times and will most likely watch it again in the future. JGS and PSH had great chemistry and portrayed their character's the best IMO. I wish both remakes would have mixed it up. Anyway, I will continue on with this version and hope it will get better.
