Mouse is one giant science experiment gone humongously wrong. There is no other way I can describe it. The only factor that kept me going was the powerful performance of the leading cast. The story, after the first six to ten episodes, was a mess. Introducing Sci-Fi is a good idea, if you know what you are talking about. What the heck was the purpose of this drama?
Psychopaths are demonized in this. This is so not the case in reality. I'm sorry, but I fail to see any signs of the writers actually doing any research on the topic prior to sketching it into a story. I would've let it pass, but the "psychopath = killer" was purposefully shoved on my face more times than necessary.

This is also my very first time coming across a drama with so many dumb adults. It's as if nobody had an ounce of intellect or humanity in them.
I'm even more enraged how the very wrong message of "a killer's son is a killer" is the built in idea of this plot.

"Flower of Evil" is one drama that dealt with this topic. Do Hyun Soo is far from a perfect character and he does several questionable acts that makes the viewer's hearts stop - particularly at the end of episode one, where we truly begin to question his identity. He is not a fluffy bunny and he is definitely not 100% in his right mind, faking his entire identity.

Jung Ba Reum is a filthy character. But, he and Sung Yo Han were just plot devices at the end of the day. If there is anyone I would love to imprison, it would be Daniel Lee. Dude preached all about psychopathic genes and then turned into a hypocrite -- he used Jung Ba Reum as a murder machine, knowing well that he was the actual killer. Every single (adult and not from police station) person in this drama needs to have their heads examined. And Miss Choi Hong Ju?! Don't even get me started, yes, she was scared and traumatized, but literally egging someone else into killing others for her own personal reasons? She could've gone to Detective Ko Moo Chi and tipped him off. Instead, she played behind the scenes.
The Head-Hunter doesn't have brains to begin with, I would've smashed his head with a hammer the moment I met him, had it been me.

And his wife… oh boy. I feel not an ounce of sympathy for her. She destroyed Sung Yo Han's life. She literally exchanged her own son with someone. It's as if nobody knew what to do with children who are seemingly troubled. The teacher suggested having him taken for therapy, yet his father hit him. (He deserved a good beating, yes, but his adoptive mother knew his condition. She should've tried different methods to coax his self isolation or taken him to a psychiatrist.)
They are labelled as monsters from the very beginning. They know that there are eyes on them. (I sniff a few plot holes, but seeing where the actual purpose of the plot lay, I'll let it go.)

Jae Hoon/Ba Reum, desperately needed to get taken away from his environment, to someone who knew how to be with him. Instead, he was taken away and awaited upon as a sacrificial lamb for someone's political gain. I hated seeing the moments where his "aunt" just sat back and watched as he killed animals. His entire life was built around a lie. Yes, he was undoubtedly a psychopath. But, he would've definitely turned into someone better had he been properly taken care of. Instead, his killer instincts were purposefully awoken. And every single person involved watched the whole thing happen.
This was never addressed in the drama, particularly during the final episodes where every storyline was hastily getting wrapped up.

And Sung Yo Han… why the heck did they film the entire 6 episodes with him in plain sight? He knew that Ba Reum was the killer, knew of the organization, and never once attempted to contact the cops "directly". I knew that he definitely wasn't the killer right from EP1, when Chi Kook's body appeared in the box. But, he kept tailing Ba Reum, if what was shown in the drama had any form of truth. And Nepo dude should've just taken him in for questioning -- that would've made the drama about 8 episodes long and the case closed much faster.

Operation OZ. Damn. This is not Area 51 or Hawkins. It was lame. The Chief Secretary of the President was as horrible as Han Seo Joon and his wife. And the people with her? And the Bill? I don't even know what to say.

The drama dragged on longer than necessary. But, I guess the Sci-Fi aspect was the very main focus rather than the actual characters. Detective Moo Chi, Ba Reum and the police gang were my favorites.

My History teacher had recently mentioned her experience while working as a trainee in a school and it kept floating on my mind whenever I watched Jae Hoon. The boy in her experience, too was someone whom everyone were terrified of.

Jae Hoon was showing all signs of becoming a highly anti-social individual, but everyone easily assumed him to be a monster right from the get go. His adoptive mom apologized for not believing him, too late though.

All I could remember was how everyone in this drama were wronged. It was supposed to have the Sci-Fi tag as the very main one, since the 'killer' part was very easy to crack. I could not believe why nobody suspected Ba Reum in the Chi Kook case, however convincing he was. Or maybe I'm too spoiled after watching Saiai -- Dai-chan, the detective, literally kept his own first love and his friends as the suspects.

They should've removed all the scientific aspects and spent more time on developing the characters, the psychopath's past and the story. All in all, it was a wild ride. But, it's too frustrating.
