I have a soft spot for this one. Everyone kept telling me how the Taiwanese version was supposedly better but I never managed to get past how ugly and stupid the girl looks in it. In this Korean version of the manga, both lead are actually hot: Oh Ah Ni is silly but cute as hell and Baek Seung Ju is just... Well I never thought myself as a masochist until Playful Kiss! The best part of this drama is definitely the two leads, Baek Seung Ju being a selfish arrogant son of a *, horribly frustrating on top of being freakishly hot (not to mention that this role was just PERFECT for Kim Hyun Joong) and Ah Ni so cute and adorable in her misery and gullibility... But overall it is actually quite childish and the supporting roles are often really annoying (when re-watching it, I always skip those parts) so don't expect something too perfect. I think the drama was stopped before it could run its course and that is why they made the special episodes that are actually the rest of the manga and as important as the rest since for once you get to see what happens AFTER the happy ending. Now PK makes the top 5 for me because of the intensity of the chemistry and tension between the two leads (so important when watching a romance drama) but others might consider it too childish. In any case, it is still a very good one for school/romance/comedy fans.
