Although it might not be very original but the thriller concept of how blood relation might overcome conscience and common sense is still a fine concept, it's just in that matter, Gongbeom stands in a gray area. If it was to emphasize on drama, it lacks character digging and believable motive along the storyline. If it was to emphasize on thriller, it lacks suspense and shove up the climax too harshly and inconveniently that it felt so cheap by the end.

The story will left the viewer many questionable logic flaws here and there, which is inevitable in order to keep the story going. There were time I have to admit some tension was flowing and put hope that it better have a punchline which would turn the movie into a powerful thriller, but it never delivered. And aside from the two main characters of father and daughter, all the other supporting characters seem to hold little to no value and make a very non-essential existence. All in all point is taken, it's a fine movie only could and should be better executed.

Daughter thinks Daddy is a monetarily driven, kidnapping child killer. While this may not be a fresh plot, this was a decent movie. It was filmed well and I felt the acting was a bit shaky but it wasn't so bad that it couldn't be overlooked. My gripes are few. I wish it could've had more suspense or darker tone for the main character. When I watch a "thriller" I want to be on the edge of my seat and this just never met that mark. I thought that it was a bit better than average but it's a movie that I'll most likely forget.

Anything (almost) that Son Ye Jin does is good. This thriller about a daughter who suspects her devoted father is a kidnapper in an old case. Things move quickly and you are kept guessing if and why. There is a good explanation and conclusive ending so you won't feel let down. Worth a watch.
