overall, it was a nice easy watch.. I think it's because I've seen too many good guy/bad guy dues fighting "serial killers" that the concept is not fresh.. and the investigation part was boring, as always, but the bromance between the mains was cute, they had great chemistry... and I liked the ending, it was not super pure good, or evilly wicked, it was well balanced.. also that door scene was hilarious, as expected of MDS ;p
also, every time MDS slaps someone I feel bad, that must HURT ;)

my rewatch value is either a 1 or 10, and this was a one time watch..
