How do I even get started? Okay, so this drama has a so called omnibus style storytelling, which means that there are a bunch of very loosely connected storylines. It's almost like a family drama without all the family relations, but darker & at times far more serious and raw. The other reviewers have made a lot of great points. Our Blues is incredibly heartwarming, borderline magical at times, has a decent dose of romance, while bringing up topics that you typically don't see on Korean TV. The setting is great, the fish market of Jeju & those diving women were rather novel. The acting is absolutely top notch, probably the best you can ever expect in a kdrama.

So why is it not 10/10?
Well, the problem is that some characters & storylines are just plain bad, there were quite a few episodes that had nothing I was interested in. Some of the controversial topics in the drama are presented in a very fake, inorganic way. I guess the educational intent is just too blatant.
