The idea of this film was very promising and attention-grabbing, especially for lovers of action films and thrillers (for me!). However, the execution and direction of this film just weren't satisfying enough.

In the beginning of the story, I was already doubtful after seeing the sauna scene - "Carter", a single man with no memory, manages to kill over 20 (probably 30+) men, all with knives and other kinds of weapons, basically single-handedly and without a scratch. Even the best-trained killers wouldn't be that capable. The opening already tells you how the story will go. The action scenes are way too unrealistic, almost fantasy-like. For a film that's classified as an action thriller, that's not so good.

The one-scene one-cut technique used during the camera work was nice and refreshing at the beginning but later on became frustrating. A lot of "empty" scenes showing empty rooms, the underneath of a car etc...just absolutely unnecessary scenes.

The non-Korean actors ruined the show for me. Their acting was simply bad, very amateur-like and mediocre.
