Excellent premise&nice cinematography. But the lead actor was disturbing at times (being so very clean&shaven throughout the film, due to how messed up his reality was).Other than that, it was an OK thriller, and I actually sense there'll be a crappy hollywood remake.
Great premise, poor screenwriting. As per usual of Johnnie To productions whether he directs them or produces them, the technical aspects of his films are superb and innovative. From music score to cinematography to action choreography. Louis Koo takes on a somber approach in his role as the leader of the assassins and becomes almost like a unsuccessful Travis Bickle towards the end. Ending is good but needs tweaking
