I loved to watch "Tell Me What You Saw", mainly because it's a police/criminal drama.
This drama is surrounded by suspense and mystery surrounding the real identity of the serial killer that is assumed to be dead but isn't. Unlike most criminal tv-shows I've watched, this drama didn't give a hint as to who the serial killer might be until he revealed himself (around the 13th episode) which was a pleasant surprise.
Now, as much as I'm a sucker for a good mystery tv-show, I felt like the number of people that were serial killers in that town was a bit overboard. I mean, how many serial killers could a town like Mucheon possibly have? Not as many as the drama showed (right?). On top of that, the number of crimes done on "The Guy"'s command was a bit surreal, like who in real life would let themselves be this manipulated to be willing to kill themselves for someone else?
Nonetheless, this drama was awesome. I loved the chemistry between the characters, so much that my romantic self had moments where it was hoping for something more between Oh Hyun-Jae and Cha Soo-Young, although it doesn't make sense to hope for it.
