When they first announced this remake of the Japanese Sora Kara Furu Ichioku no Hoshi, we were promised a uniquely Korean retelling of the storyline. I can't comment on whether or not they succeeded but there is certainly still a very Japanese flavour to this tale of a damaged advertising designer and an ambiguously-sociopathic brewer who shares similar scars.

There are two distinct and competing parts of this show and therefore this review: the first is the production overall, from the cinematography and the music to the acting; and the second is the plotting.

For the first element, this show excels at being a beautiful, compelling, moody psychological thriller with outstanding performances from all the actors involved. The directing, music and acting all combine to effortlessly create a gripping and emotional show that draws you in and keeps you watching. This show is expertly made and that deft production shows in every frame.

Park Sung-woong is always a fantastic performer in everything he does and he brings out every layer of the complicated and conflicted Yoo Jin-gook, a detective and older brother of the female lead. Jung So-min is very good as female lead Yoo Jin-kang who is drawn to but also wary of Seo In-guk's complicated anti-hero Kim Moo-young.

But it's Seo In-guk who really shines in this. In fact, it is the performance of his career. Ziggy is well known by now not just for acting a part but for living it. He doesn't create a new person, he completely inhabits them down to his fingertips. But even knowing that about the actor, this is still a tour-de-force of a performance - one that propels him up above the regular pack of Korean actors and puts him into a class of his own. After this drama, there are few people who would argue that he is now on a different level - one inhabited by the likes of Yoo Ah-in and Bae Doona and even Park Sung-woong himself. If it is possible for an actor to have a new breakout role - one that doesn't launch his career but that finally takes it into orbit than this is it.

It's difficult to discuss the other elements of the show without spoilers - and this is one drama where the wrong word can potentially ruin it for any future viewers. However, beneath the fantastic production values and Ziggy's blazing acting triumph, this show struggles with its plotting and characterisation. In some respects, this is due to its source material - Japanese writers tend to create strange, almost surreal characters that only infrequently behave like normal people. This somewhat wars with the Korean sensibility in the back half and the plot falters as well. Combined with opaque character motivations this can make a lot of the episodes frustrating to watch.

Regardless of how poorly the back half was written and how dissatisfying the show was overall, the show is entirely worth watching for Ziggy's mesmerising extraordinary performance.
