Big Mouth got off to a fast start. I liked how the story introduced Park ChangHo's character and how abruptly everything changed. What a crazy ride it's been! From an incompetent, debt-ridden lawyer, he was tagged as one of the most notorious criminals in the country, Big Mouse. Every episode was fascinating and heart-racing, adding layers to various mysteries.
The story's progression was intense, continuously pulling viewers off-balance with puzzles to answer, which may have been too much because the ending didn't do it justice. This might easily have been a 10, but the finale left so many loose ends. Although I don't have a problem with Ko MiHo's death, the ending felt rushed. Again, they mentioned the elderly man's serial killer son, but he didn't appear, which confused me because he seemed vital to the plot. I also despise the fact that no one appeared concerned about HyeJin being murdered by her husband.
Aside from these flaws, ChangHo's character development was excellent. It's an incredible depiction of how desperation and the struggle for survival affect people in extraordinary ways. This was exciting to see that the main topic wasn't the revelation of Big Mouse's identity, but how ChangHo himself changed to be his version of Big Mouse.
The dynamic between ChangHo and JiHoon was fantastic. What an unusual and powerful relationship! Although I wish we had spent more time on this bond. I particularly enjoyed the friendships created between ChangHo and several of his fellow inmates. I always love seeing characters develop positive relationships.
All of the actors gave outstanding performances, particularly the female leads. Lee Jong Suk's best work to date. Kim JooHun acted magnificently, as usual. I swear I wanted to kill his character myself.
Overall, except for the final episode, this kdrama has been nothing short of brilliant.
