My initial thought right at the time when the movie ended- "That was indeed merciless and monstrous" and then I recalled that the name of the movie was itself "No Mercy". At first I want to state that this drama is not for the ones with a weak heart, irrespective of the gore, this drama possesses a bitter taste to the bile and indeed this is highly recommended to the strong hearted ones because you won't regret it. This movie recommended to me by a friend and truly I wasn't held back from my position for even a second. If you like crime thriller and deep devotee of the classic Old Boy (2003), then this movie is just the one for you.
