The plot is innovative, the characters not that much.
What was that ending ??? How can a film end on such a cliffhanger ?? It’s not an open ending at this top !

The plot twist of Jun-yeong not being actually who we thought he was was such a good idea and made me increase the rate by a little a though it was dropping since the moment the cops started to plan something to catch the culprit.

Then talking about the cops, I can’t explain how much I HATE and DESPISE jun yeon’s father ! His character is so useless, dull, dumb and does nothing but cry.
