I would say that Mouse was able to reach the expectation that I have set for it though there are some parts where I wish its much more unique rather than predictable. This drama is definitely something that is worth watching though sometimes felt dragging, due to its theme and the serious nature. Regardless, it was a very solid drama, where the acting is on point, the plot was somewhat predictable (e.g. Bareum being the killer) but I really like the concept of integrating the "Lab Mice" concept to people and obviously it is not morally acceptable but its a fresh concept in a K-Drama given that the theme of murder and serial killings is common.
