I guess the reviews are mostly so negative because a lot of people had high expectations in the cast and the fact that it is an adaption. Not saying that the drama is bad, but that people probably just expected something much different.

I mainly knew what I was getting into, though I hadn't watched the original adaption, but there is not too much of a twist to expect about a drama that focuses around rich people. The Greatest Seducer was a good drama. I loved it. I felt a whole lot of emotion from happy, anger and sadness. It is definitely not the greatest drama that is out there, but it has all the qualities all good dramas have. A good cast and good acting, and an interesting plot.

I know a lot of people hated Joy's acting, but she did very well, actually. Most people just dislike seeing popular idols in lead roles, what I get to a certain point, but I could also give you the names of three "veteran" actresses who are in my opinion worse and loved by millions.
The storyline was nothing new, a lot of intrigues, tragedy and drama but also a lot of cute romance and funny side characters. Since it's an adaption after all, I am really surprised by most of the reaction to the plot, besides that, just the fact that this drama is about chaebol problems gives you enough information about what this drama was going to be - like I said.

What I liked the most was our female lead. TaeHee is a strong character from the beginning, and she mainly stays true to it. I read quite a few reviews about TaeHee being annoying and dumb, but I guess the world is just not used to a female character that is strong but also vulnerable. I never doubted TaeHee's decisions because it all fitted with her experiences and morals. SiHyun was a character with very good character development, and it was very nice seeing him grow up and embracing his problems. The romance of the leads is built very nicely and in my opinion pretty realistic for a first-love type of story. As much as I loved most of the drama, I do disliked some parts. My biggest problem lies with the side characters. For me, it seems like the writers gave much thought about how they wanted to develop the main couple, but gave very little thought about every other character. Especially our antagonists, they were all just driven by love which blinded them to a point that it was ridiculous. Even though they had major story lines, a lot of characters were just so unreasonable that it was difficult to understand where their problems, angst and difficulties lied with. Also, a lot of the problems stay unresolved, and I feel like even quite a few characters get forgotten throughout the ending.

After having watched the original, this is still better.
Overall, The Greatest Seducer did stress me out at parts, but I kept coming back for all the tea. I don't regret any minute of it.
