It had a decent start setting up the atmosphere. The drama was shot nicely too, try to grab the UXN 4K version if you can. The action was good although it was scarce. There was a lot of downtime between each event which almost ruined the drama. It was clear they had an abundance of free time that they started supplementing it with slice of life/comedic moments which were straight up bad and unfitting. The story wasn't as engaging as it was at the start, it somehow lost its direction midway through. Too many plot holes to count even when excluding the supernatural elements. The drama lacked a meaningful connection between characters. The least you would expect from a military themed drama is some comradeship which this drama failed to show. It's a hard watch since the drama doesn't have much to offer other than a good cast.
