Big Mouth is one of kdrama that have promising plot at the beginning. The Plot "Who Big Mouse" delivered very well, keep you wondering who is the BM and why they do all his things. I love the character development of Changho, and power couple as Miho beside him. I love the suspense and how the political issue in this drama satirzie the real political issue in real life, sad but very true.

But after the BM revealed, the plot become very basic political mystery kdrama. Suddenly the plot "Who BM" just there so Changho get the power againts the villain. BM who intruduce as the powerful, intimidating, mysterious, smart ass villain become so called mafia group that we even didnt know from whom and why they have their power. Doha as final villain become so bland, another pyscho devil villain to hate.

The ending, is one of the thing i cant let it go. I mean i even didnt hope for happy ending, but this ending very rushed. Because of duration, i didnt feel the saddness and sorrow of Miho death, is not like Changho didnt sad, but the way he sad at the moment of Miho death just like producer told him to not really sorrow because he still need to kill this evil villain Doha to save the day. There still mystery that didnt solve at all (Hyejin death, Mr. Park and etc). To many mystery told none of them solve.

I feel if in the end of the day, this drama just want to focus to Changho againts Doha, the plot "Who BM" should revealed sooner, so that the solve of main plot Changho againts Doha become more intimidating, clear and maximum.

Big mouth still good political mystery drama, there some moral value and satizire to society that i love. But i didnt wanna rewatch this or recomend this drama to another ( didnt really worth the time). Overall 7/10
