Mouse Review (Spoilers included)

The subject matter was good, but it was boring.
As many people have mentioned, it dragged on too much. About 6 episodes would have been perfect.
The flashback scenes and nightmare scenes were tedious. Plus, they appeared too frequently, so I didn't like them.
Since the chase scenes for each character appeared in almost every episode, they became boring at some point.
The undying killer who appears whenever something important happens
actually felt like it broke the momentum. It disrupted immersion and had zero tension.
Lee Kyu-hyung's portrayal was constantly stubborn, arrogant, and shrill, which I also didn't like.
The character development lacked persuasion.
I wonder why they included the group fight scene in the latter half? (I don't know the original work)
No Ja's acting felt like Kang Chul-jung as it went on, but his chemistry with Moon Jae was good,
and Kim Sung-oh's acting was very gritty and impactful.
