This is a classic and maybe it was one of the first to feature these now common themes and tropes in k dramas (like the evil MIL, love triangles, and self-sacrifice), so that's why it's so popular. It was one of the first dramas I ever watched. I recently watched it again and decided I am no longer a fan of it.

I do like Ha Ji Won and I see that she is a strong female lead actress. I also liked Yoon Sang Hyun's portrayal of his character. He was romantic and lovely. Surprisingly, I thought Hyun Bin's performance was one-dimensional and uninteresting, but I believe it was due to the writing and script.

The leads don't have romantic chemistry at all. It was written that way and it simply doesn't work. There is no reason for the two to be in a relationship. I can't stand the continuous physical and sexual harassment that happens throughout the show. While it is still prevalent in some current shows, it is pretty unacceptable. The bro love is strong and the dialogue between the two guys is interesting and well written, but the delivery is pretty much yelling at each other the entire time. Ra Im and Oska have the strongest performances, but they are wasted on their lovers because of such a lack of chemistry. One thing the show does have is endless twists and turns in the plot so it doesn't get boring that way.

All in all, I would not recommend this show except to see what dramas used to be like and how far they have come.
