I started watching this drama with expectations. I saw many people suffering headaches throughout the episodes, and it turns out I experienced the headaches too!?
Mouse is not your usual crime/thriller/action drama. It gives you goosebumps, confusion, and like I said: headaches!!
If you are intrigued to watch this drama, please know that this drama is dark, confusing, scary, cruel, and triggering. And if you are not a fan of a crime drama but just wanted to have a little twist to your genre, this might not be the perfect drama as it is a very heavy drama.

I am a big fan of a true crime movies and drama, and to put it simply: read my headline. This blew my mind. Every story, every step the characters make, every word, every thought, it has meaning at the end and whatever you expected: it will exceed it. Some characters might not seem important to you or some might be very important to you, but it won't turn out that way, and I for one experienced that myself.

While watching this drama, my only problem was the length of each episode, which is around 63-100 minutes and that some scenes were not necessary. But it doesn't change my view towards this drama, as it has perfect plot twist, and perfect acting shown by Lee Seung Gi and Lee Hee Jun.

This drama gives the perfect amount of emotions: sad, happy, awed, exciting, anger, and confusion. I'd easily give this drama a 9.5, mostly for the plot and the acting. One of the best crime/thriller k-drama for sure.
