Big Mouth is a drama that attempts to say a lot of things and use a lot of themes, all of which end up falling face first into the ground. The plot reminds me of a typical badly produced mid 2000s drama. It doesn't know what it wants to be and everything about it is so uninspiring and empty. Does it want to be a murder mystery? A crime thriller? We're in a prison now, does that mean our cast will do something within the confines of this place? The drama tries to use these genres all at once and ends up feeling like a waste of time.

The pacing is bad even by kdrama standards. The first half of the drama wasn't that bad since it felt like it was building up several different mysteries that we as the viewers could speculate about and see how it all ties up. However, the latter half is just a horrible mess, which I'm sure a lot of people have commented about but I'd like to say it again: the last few episodes of this drama is quite literally unwatchable. I could not stand sitting through these episodes and watching them flail around trying to give the viewers a satisfying conclusion. I know a lot of people struggled to finish the drama purely because they wanted to see the romance, but I'll be honest and say it wasn't even that good at all. Just your average kdrama romance that didn't tug at my heartstrings and only served to move the plot forward.

I've watched Lee Jong Suk across multiple dramas and I'm not trying to be rude when I say this man should stick to his romance focused genres. I appreciate him trying to branch out to a new genre but he just didn't impress me with his performance here. His character isn't the least bit charismatic, which is surprising considering LJS almost always has a certain charm to him in other dramas. Instead we get an annoying parasitical manbaby who I could not care about in the slightest. Yoona as Miho was nothing special either. She did her role and I have no majorcomplaints, but I already know I'll forget her performance in 3 weeks. The weird slowmotion and closeups for the "look at how cool our main characters are!!!" scenes didn't really get me? Guess it'll make for some good edits on youtube dot com. The rest of the cast was boring even if they had decent acting. The side characters are forgettable, the villains are cartoonishly evil (as per the usual kdrama standards) and the big reveal on who Big Mouth was soured my entire day.

Tl;dr Big Mouth was created by taking everything bad about Pretty Little Liars and I wasted 16 hours of my life watching it.
