Big mouth ( 빅 마우스, Big mouse; literal title) is one of the most awaited drama due to almost every reason of it. The story is written by jang young chul and jung Kyung soon. Vagabond and empress ki are some of their best works.
On the other hand this is directed by Oh choong wan previously worked with Lee Jong suk in the drama, ‘ While you were sleeping.’ Hotel del Luna and start-up are some of his other works.

Story:-
Story is the best feature of this drama exploring the expedition of whole characters in search of Mystery character called Big mouse.
Starting out as a simple drama, in no time it pulls you in in the quest of figuring of the mystery man/women/ghost/organization.
Park Chang ho, a quite ordinary defence lawyer with the nickname *big mouth* due his big talks, while solving a murder case, gets framed as a biggest con man in the history, Big mouse. Thereafter story progresses as Big mouse keeps everyone shocked with his wise revelations of the conspiracy.
Each episode, though reveals something, gets confusing and hard to figure out who Big mouse could be? Making us feel suspicious about all characters, even those who bear a veil of innocence. This thing about this drama keeps you on your toes to see what’s coming out in the next episodes.

But the drama has it’s own flaws, like there has never been any certain scene that proves park Chang ho and ko miho are intimate or even married. At times this makes it even worse by the use of few formal dialogues...this makes you feel uneasy about their relationship to stay at one place... Anyway this has never been a marking part of this drama.

I would say the ending is a bit unsatisfying and rushed ofc. There are no PROPER explanations for some of the actions and questions arising in the first half, like what was the significance of those papers?
Besides giving off a blast about conspiracy behind it. And why didn’t Hye Jin get the justice for her death? I mean she just died for like an unnecessary reason.

Even with all those loopholes this drama keeps you tied to it to urge to watch next episode. And this is the mystery of the year to me.
Still not solved though....

Acting:-
Lee Jong suk: He has returned to small screen almost 2 and half years later. This is one of the marked reason that this drama has gotten a wide attention due his big fan following. He has been my bias for quite a long actually, so I am totally impartial in his case, though I’ll try to keep it simple.
He has performed the character very meticulously. His expression and some acting corners have also improved over the time. Lee Jong suk has always been choosing versatility in character and he aced in this one as well...

Go miho is the most important character in opinion and if Chang ho is the Big mouse( Big mouse is still not certain to me), she holds all answers to it... Sad it ends with her... Her acting, though poor at the beginning, gets better with every coming episodes.

As for the other actors, I would say I’m not satisfied. Not entirely though. Drama didn’t really explores their background, thus making them insignificant at the start...
( I guess this was necessary for the story being mystery thriller.) Still this is the disadvantage to the drama...

Ost & music:-
The only ost this has is ‘New face’.
It gave me goose bumps while playing in the drama. Certainly not the best but good for what seems mysterious....
Bgm is quite good. It is one of the factors that gets your brain engaged it the story.

Re-watch:-
After all this, this was nothing but just a bluff, quite fascinating though. I am unlikely to come here again for the second watch and don’t even want the second season except for some explanations if they can give...

But I will definitely recommend this to everyone for their first watch keeping in mind that this is not the best but a good drive if you want to enjoy mystery thriller and Ljs visuals ( btw he has gotten a bit chubby on his face, that doesn’t degrades his killing handsome )

Lee Jong suk fighting!!! :)

Thanks for coming here.. Happy watching..!
