I started watching without knowing anything but the title and the picture that goes with it-- and I dd not regret a single minute!

What I liked best:

* The initial premise is different and interesting, the story arcs well paced and in the end, all story threads are neatly tied up. Even if they ended the series with a glimpse of a new plot, it felt more like a "this is not the end" than a cliffhanger.
* The main character was extremely well acted, I loved the facial expressions (or, sometimes, the lack of them) and how the actor moved his body, we never forget that this is actually a dead body, not a living being.
* The comedy was there duiring all the episodes, and varied between spoofing Zombie movies and the detective genre, slapstick-y routines and just plain hilarious situations.
* The mysteries were not too simple, but simple enough for a comedy.
* Some K-Dramas I've watched have a weird slump in pacing or story in the 9th to 11th episdes. This one doesn't, every episode was interesting or funny enough to keep me watching.
* There was no romance between the two main characters, only a hint of interest on the woman's side, which is not even recognized by the zombie detective.
