The film has a good premise, but the runtime is too long and the pacing is somewhat slow, by the time the movie reach one hour or so, you are already bored to death. the plot is not that complicated, it could be told in an hour and half at best.
There was a forced twist halfway through the movie, that made the whole thing personal to the protagonist. The chances that the protagonist's father and the bad guy having an accident in the middle some road, are gigantically low but it sorta just happened here. The movie gets overly dramatic sometimes, and the protagonist is somewhat unlikable, at times I find myself rooting for the bad guy. I don't understand why some characters have to behave irrational to prove a point or to show their disappointment eg hitting someone with a book, slapping a person, pushing them etc this is common in Korean movies I don't know why they have to act like, so irrational.
The characters are well-developed, and the actors did justice to their respective characters. the cinematography was excellent, the cool cars and awesome car chase scenes were a treat to the eyes. There was a hint for a sequel, which I highly doubt it's going to happen.
