I am surprised that I liked this drama as much as I did, because I usually can't stand stupid female leads. Jung So Min is so cute that she made her character very likable, in spite of her pitiful behavior. Kim Hyun Joong plays cold/arrogant really well, and I couldn't help liking his character too (his smile is killer!). Together they had an awkward chemistry that I think worked really well. I also liked the supporting cast of family, friends, and rivals, but Wang Kyung Soo was distracting because he couldn't possibly pass for 21 years old. Lee Tae Sung's Oh Ha Ni-obsessed character was annoying at first, but eventually he started to grow on me, and I was impressed by how different he was from his character in "Romance Zero". I absolutely loved the mom as well, who was definitely one of my favorite characters. I started to miss the band after a while too... : ) This show basically is about stalking, so if you don't find stalking cute/romantic, then you will probably hate this drama. It takes the opposites attract theory to the extreme, but as the story progressed their relationship started to make more sense. I haven't seen the other versions, or read the manga, so I can't compare it. I wouldn't call Playful Kiss one of my favorites, but it is worth watching. *beware of fan commenting, especially if you are unfamiliar with the story, because they end up spoiling everything!*
