BIG MOUTH refers to Park Chang Ho, as he is known to talk big but can not follow it up. He’s also a lawyer with a very low winning rate. One day, he was framed as a notorious swindler "Big Mouse" and sent to prison. Since the real “Big Mouse” is still a mystery, his wife Mi Ho is now struggling to prove her husband's innocence…

First, the premise is gripping as we quickly presented with the big question "Who is Big Mouse?“ It kept me wondering on who is Big Mouth and his motives. I enjoy seeing Chang Ho’s gruesome experience in prison and his dynamic with his wife, Mi Ho. I love the suspense and how they address a realistic political issue.

Then the reveal happened and it was so underwhelming... It feels that the drama lost its’ steam. We were introduced to so many plot points but it continues solely on hero vs villain plot, while sacrificing some characters at no cost. There’s a time jump towards the ending, and all that happened afterwards made me upset. The sequence of events were rushed and the huge blow I was expecting feel a bit off. Had they build up the finale properly, I’m sure it would’ve been more impactful.

This is my first Lee Jong Suk dramas and his psycho acting was entertaining. Apart from him, the acting of Kim Joo Heon was enjoyable, especially his fake crying and facial expressions. Overall, Big Mouth shows amazing performance and story until the reveal happened, so take my thoughts with a grain of salt and feel free to watch it!
