Not to be mistaken with the American animated series, Big Mouth is titled the way it is not because of raunchy banter between its characters, but because the lawyer protagonist Park Chang-ho spouts big talk without having the means to back it up. It’s because of this unusual characterization that makes it such an unusual crime thriller, with wildly unpredictable turns that got so many viewers guessing and that the showrunners clearly had fun playing around with, with every terribly unlucky direction Park ends up taking. That being said, while its set-up was so exciting, Big Mouth is much like its protagonist in that the series promised a big story, but winded up with an underwhelming finale that didn’t meet expectations. Even so, Big Mouth is a hilariously intense, if a bit nonsensical, ride, especially for fans of the cast here.

The ending was so underwhelming. Ko Mi-ho deserved better.
