I will confess to watching quite a few kdramas and the fact that very few of them make my list of re-watchables or ultimate all-time favorites. And I'm happy to admit that I hear your voice makes that special list comprising very few names. It has everything - i)a recurring theme of justice, notions of culpability, a moving discourse on the thin line of difference between fair and unfair and the human desire for connection ii)A solid ensemble cast who put up stellar performances (Lee Bo Young is outstanding as the prickly, smartass, intelligent, independent modern woman and so is Yoon Sang Hyun as the goofy but upright defense attorney. Lee Jong Suk is quite convincing in his difficult role as well) iii)A well plotted story that makes sense and doesn't frustrate us with its lack of rationale. iv)great music which goes with the overall tone of the story and adds to the many tender or suspenseful moments that the characters share with each other AND last but not the least..... v)a heart-melting noona-dongseng romance. If Soo Ha and Hye Seong's romance didn't move you or you are still cringing at the age difference thing then I'm sorry to say you're not a very sensitive human being. So if you're still hesitating and wondering whether it's worth a shot to invest 18+ hours in this specific drama, do not worry and JUST GO RIGHT AHEAD AND WATCH IT. This drama gifts you with an amazing, amazing experience, teaches you lots about human empathy, nitty gritties of the law and the ultimate need to hear and respond to someone's voice (be it a stranger or someone you've known for ages) (Yeah sorry couldn't help but use that cliche)
