Unfortunately, this show lacked to deliver on all points. Full of movie cliches and lines. I should have stopped watching when I saw a body fall from a high building. And how does a body fall..... Exactly: always on it's back on a parked car. Sooooo boring. Maybe this show was aimed at a teenage or younger audience.
I kept on watching because I admire Kim Sang Ho. He is absolutely great. But his performance couldn't save this show, neither could the excellent performances of these very good actors Kim Chang Wan, Choi Kwang-Il and Kim Tae-Woo.
Lee Se-Hee was at no point believable. Definitely not as the superior of the main character. Do Kyung-Soo made his character much too slick, totally unconvincing. Too cliché in his sort of arrogant teenage acting showing too much an almost frightening twisting of his lips especially on his right side, making it look like a super enlarged mouth twist of an Elvis having Parkinson.
I was hoping it would get better, but this TV series looked like a video clip for Do Kyung-Soo, who has still so much to learn where acting is concerned. Ha Jun looked more promising to me. He was definitely much more in the moment; controlling his world as Oh Do-hwan, but he also doesn't have the depth of a solid actor yet. But I'm almost sure he will.
The camera work wasn't too impressive I'm sorry to say and the directing lacked to give any surprises, although the many ridiculous plot twists may let you sniff at.
All in all, a very bad show if it wasn't for the excellent performances of the actors, I've mentioned in the second paragraph. One point each for those four actors.
