A Shop for Killers is fantastic. I watched it and regretted why I hadn't watched it before. The action in this manga is truly epic and mind boggling. I hope they make a second season because I just can't wait to see what will happen next, This show is extremely thrilling and will make you want more. It kept me on the edge of my seat for the whole day. In some Korean dramas, even getting a gun is a pain in the ass. But in this drama, a pistol is the most basic weapon, while we have mercenaries with machine guns, attacking drones, and whatnot.
The negatives of this show are probably some far-fetched plot holes and pacing. Because I think some people don't watch it in one go and might forget the details with flashbacks going on and off simultaneously. But otherwise, the drama is French's kiss, with great actors and superb direction. I'm in love with characters like Minhye, Bale, and Pasin.
