I'm into crime-thrillers & mystery dramas lately. I've been reading discussions about Mouse in this thread.
It's mind-boggling! You have to guard your emotions esp when you review the preview stills. I just blurted WHAT!??!? :-D
This drama is a good example of "this is the truth, are you still hoping for redemption?" Go Moo Chi is my fave character.
Lee Seung Gi's performance is over-the-top. What a way for him to show what he can really do as an actor.
I don't think Mouse is overrated. The story is intended to be written & executed this way because we are learning a lot about a psychopath's behaviors. Very detailed and active.
