The series tells the story of an underperforming lawyer who gets caught up in a murder case. In order to survive and protect his family, he digs into a huge conspiracy among the privileged upper classes.


Big Mouse is fueled with mindboggling storyline, unpredictable plot, and impressive performances from the cast. It was like a huge maze that will confuse you but at the same time it will keep you guessing while toying with your emotions. The whole series was wrapped with high-octane scenes. The explosive twists and turn of events will have you on the edge of your seat. It has all it takes to be the best, unfortunately, it unravels an anti-climactic ending. It was filled with inconsistency, the story was wrapped up in a hurried and lousy manner, and there are too many plot holes. It left a lot to be desired. An intriguing slow burn thriller that failed to tie up all lose ends. In spite of that, Big Mouth is a gripping show that will pique your interest until the very end.


At the beginning, Big Mouth is wearing a full gear ready to battle to be one of the best thrilling KDramas of all time. Unfortunately, it failed to do so. It started really strong. It has all it takes to be one of the best. I love how the story was laid out in the beginning. It was intense. It will truly engross you every second of it. It was indeed unpredictable. You won’t have any idea where the story was going. It will send you to a turbulent of emotions. The show itself is like a puzzle. You will try so hard to find the correct pieces to suffice the central mystery. Watching this show is also like becoming a mouse escaping a confusing maze. You will take part of the story. It was indeed immersive. That’s why I have high expectations about this drama. Don’t get me wrong. Big Mouth was still a good watch, its just that the plot holes and inconsistencies overshadowed the positive points of this show.

From left to right: Kim Joo-hun (Choi Do-ha), Im Yoon-ah (Ko Mi-ho), Lee Jong-suk (Park Chang-ho), Yang Ok Ja-yeon (Hyun Ju-hee), and Yang Kyung-won (Gong Ji-hoon).

One of the strongest suits of Big Mouse is its stellar cast. Every each of them did good job in their respective roles. Let’s talk about the actors that deserves honorable mention. Let’s start with Im Yoon-ah. She did so well. I love how subtle her role was and when it was time for her to shine, she become unstoppable. There are moments were she totally stole the show. I know that she has a lot more to offer. Yang Kyung-won is indeed one of the reasons why this show became more fun to watch. The way he lend comedic relief to the dark tones of the show is impressive. He proved that he is not only a great with comedy, he also showed his potential in this kind of genre. He balanced the heavy aspect of the show. Kim Joo-hun is without a doubt an effective antagonist. His character was well written and he performed really well. He is so good to the extent that he will also deceive you. He add flavor to the plot. And lastly…

Lee Jong-suk as Park Chang-ho

Lee Jong-suk’s comeback is truly worth the wait. If the discussion is about range in acting, he should really be part of it. I think, everyone would agree that Big Mouth is his series. He is the highlight of the show. He embodied the character of Park Chang-ho so well. His versatility is unquestionable. The way his character shifts from being bright to someone filled with darkness is just brilliant. You can really see the distinction of his portrayal for the character of the lame Chang-ho and fiery Big Mouse. From the mannerisms alone, you can say that he knows what he is doing. He can make your heart flutter, at the same time, he can send shivers down to your spine. His performance was believable. There are times when I am in awe from his acting. I never thought that he can be this great!

Like what I’ve said earlier, this drama is indeed worth-watching. Its just that it left a lot to be desired. There are still a lot of questions left to be answered. My main concern lies with Mi-ho’s death. I don’t know what is the significance of her death. The plot will still remain as is even if she was alive. Did they only do that for the dramatic blow? I am quite disappointed because it started really promising. It stumbled really hard towards the end and it was unable to find the right path. I just hope that they tied up the story more neatly. It was shining so bright at first then it suddenly dims in the end. Nonetheless, Big Mouth succeeds in giving the viewers an engrossing entertainment. I would still recommend it.

Rating: 3.5/5
