Overall I thought this show was kind of decent. It has parts that were really good and other parts that were just okay. This drama essentially revolves around a team that goes out to catch people who commit insurance fraud. Just as mentioned in the synopsis. You sort of see this at a case by case basis at the beginning of the drama. As we proceed closer to the end we see a big overlap of how this one fraud case caused many deaths and casualties that affects our main characters.

Story [8.0/10]: The story wasn't too bad, but it's definitely not anything new. It's your typical crime drama that you often see. It often starts out with episodic cases that the main cast is trying to solve. Eventually some cases may begin to overlap and then play a larger role in overarching story. Mad Dog really isn't too different from that. In my opinion, this story lacks a little bit of rising action as well as a climax. With dramas like these, you generally have the same recurring problems. You know what happens at the beginning and at the end. The drama's job is to often tell you what happens in the middle as it helps you fill in the dots.

Acting/Cast [8.5/10]: I was more of a fan of the cast than of the story. I'm a big fan of Ryu Hwa Young who recently starred in Age of Youth as well as Hong Soo Hyun. I became a big ban of hers after watching The Princess' Man and History of the Salaryman. I only wished she got more leading roles. The male actors are not too bad as well.  Jo Jae Yun is also one of my most favorite supporting characters. He's absolutely hilarious and he's the same here too while playing "Cheetah" in the drama. There are hints of romance, but there really wasn't too much of it between two of the main characters. The acting was very good as well considering you had mostly seasoned veterans playing the main roles.

Music [8.0/10]: The music was so-so. I pretty much give the same rating to most music in dramas unless it has a nice OST, is a music drama, or just has really really good songs.

Overall I was decently glad that I watched the show. It kept me mostly interested the whole time. Although I more so watched it to see my favorite actors and actresses rather than for the story itself. This show was definitely more about the characters than the actual plot.
