I'm going to try my best not to rave about this comedy. If I fail, sorry. Let me state clearly that it's beyond rare that I give anything all 10s. I mean RARE as in haven't done it in years rare. Is Sound that good? You damn well better believe it. This show is funny. BUT you have to like stupid funny. What I mean is you have to like laughing at things that are so improbable they are hilarious. Liking some toilet or bawdy humor isn't bad either. Remember this was a 15 minute web series. It didn't run on SK tv so they pushed the Korean envelope a bit on things they could and couldn't do and (pretend to) show. As a struggling web artist Jo Seok (portrayed by Lee Kwang Soo) lives at home with his parents and younger brother. The show is about things that happen in his daily life (and to some extent his family's lives) as they all go about their daily routines. Lee Kwang Soo stood out to me when I first saw him in City Hunter. I don't know why; he just did. He quickly became one of my favorite cast members on Running Man. Since then, I've seen almost all his series and a fair amount of his movies. His acting has gotten better and better. As the lead in Sound, he's perfect. The cast he leads which includes the phenomenal Kim Mi Kyung. (I swear she is the hardest working woman in South Korea) are equally as perfect. This is the odd case where the casting director got it right all the way around. Speaking of RM, ex-RM, Song Joon-Ki is in an episode for maybe 2 minutes. Current member Kim Jong Kook is in another episode for perhaps 10-15 minutes. That brings me to the episodes. The webtoons were 15 minutes. Luckily, I found 30 minute episodes (2 web eps put together of course). The writing is fantastic. There are some crude scenes (remember that potty humor I mentioned), but don't let that deter you. Those couple of scenes are really setting up something bigger and funnier. WARNING: The funny may sneak up on you. I started watching Sound at work. A scene came out of left field and took me by surprise. I basically holler laughed and had my supervisor at my desk wondering what I was doing. There's very little character development as it's not that kind of a show. There is character familiarity. You get to know these characters quickly as you do if you were just starting to read a comic or watch an animation. Hopefully, there will be more seasons and we'll see them develop. The music was good... I guess. LOL I remember there was music and it fit well. I didn't find it hokey or silly. Just appropriate. Overall, I adored The Sound of Your Heart. For me it was the perfect 30 minute nugget to help get me through my days. I've actually watched it twice in less than 2 weeks. I guess the rewatch factor is kind of high, huh? ;-) Mind you, the type of slapsticky comedy might not be for everyone, but you never know until you try.
