I put off watching this show for quite some time because of how thoroughly mid the ratings and reviews are. Imagine my surprise when I fell completely head over heels for this series after the very first episode.

It's a very quiet, slow story with a lot of lingering shots and silent moments which in a lesser show could very easily have become boring and repetitive, but here, thanks to fantastic acting performances by the entire cast as well as the precise editing, serves to build atmosphere and tension expertly.
Which is not to say the entire show is tense and dramatic, oh no there is plenty of charming, understated humour as well as some perfectly timed non-verbal comedy which genuinely made me laugh out loud.
Through most of the story the characters talk to each other fairly little; instead, the writers take the show-not-tell approach and let the audience get to know the characters through flash-backs and small, silent interactions. This not only serves to highlight the acting prowess of the cast, it also helps build a certain level of suspense as well as drive the plot - the main characters are two people who are, understandably, hesitant to be open and direct with one another and their small, increasingly intimate quiet exchanges eventually culminate in a highly emotional conversation when the two are finally able to communicate clearly with one another. In fact, they talk specifically about what led to their miscommunications and reflect on what they should have done differently so as to avoid further problems and give their relationship a real chance to succeed. This scene is a great release of tension and, in my opinion, a very satisfying pay-off.
One of the biggest complaints people have about the show seems to be the big kiss that happens here and I agree, it's bad.
But personally I don't think it spoils anything. These two are not afraid to get close to each other, we see them get physically close and touch casually repeatedly during the show and there is a clear intimacy and palpable romantic tension between them.
It is also neither the first nor the last kiss the two of them share and I feel their final kiss specifically is incredibly sweet, so I honestly don't think the "big bad kiss" is nearly as much of an issue as people make it out to be.

In short, if you want a highly character-driven story with great acting, solid visuals, lots of subtle (and some not so subtle) humour, and an incredibly charming slow-burn romance, then this show is for you!
It's obviously not perfect, but it's clever, sweet, and fun so give it a go, I honestly don't think you'll regret it.
