I watched this film knowing nothing about the plot, and the premise got me immediately hooked. A killer gets hired by suicidal man to kill him, as he has a "theory" that he cannot die, and will only be able to die once he does not want to die. The killer man job is to figure out how to kill this man, i.e., how to make him not want to die and then kill him. The killer tries to kill him a couple of times, not believing the theory, but fails, until the hard evidence makes him start to consider the theory.
Once the premise is established, we get to know little by little the background of both protagonists, and discover how they are somehow connected, and poses the questions is everything happening for a reason? Or is it us that we give reason to the inevitable coincidences that occur in our lives? This is done not subtly at all, but it's a good question to be asked.
In the end, we reach a resolution though a series of events that are connected for a reason, or in the other interpretation, through a series of coincidences too strong not to think they were meant to happen.
My only minor criticism is that the "twists" are very predictable, but this is minor, since possibly the intention was not to give a shocking twists, but to show how a series of unlikely connections makes us wander if they are happening for a reason, the main question of the movie.
Quite interesting though not spectacular film, it did leave me thinking a bit, and I enjoyed my time through the darkness of the tone, the character development, and the questions thrown unanswered by the movie.
