Overrated? not sure, kind of feel like it's in the middle. One of the best performances by Lee Jong Suk seen by him. He really grew on me this time. I admit I was kind of so/so with his acting and I mostly saw a pretty face, but in Pinocchio - he surprised me in a good way big time. I don't think I will rewatch it as this series did not grab my heart as other dramas did, but saying that - I enjoy the drama very much. The story was interesting (unreal a little) but hey, why not having fun once in a while? Both leads did good job, the story was mysterious till the end and the ending satisfactory. Both leads looked pretty together. Chemistry? Yes, but more like a brother sister relationship or older father figure type of thing... I admit kissing scenes were much better with lead actress. She really improved in that area. She also looked like she suddenly looked prettier then ever. Young people in early 20s would enjoy the drama more I think. For a mid age cute chick as myself - it was a good but not memorable watch :)
