I Saw the Devil (Korea, Magnet/Magnolia, Blu-ray or standard DVD, NR, 142 min.). Korean star Choi Min-sik found international fame as a man bent on revenge in Park Chan-wook’s film “Oldboy.” Here, in director Kim Jee-woon’s wildly violent, genre-pushing vengeance epic, Choi is the embodiment of murdering, torturing evil, and Lee Byung-hun plays the equally single-minded elite special agent seeking maniacal revenge for the death of his pregnant fiancée, Ju-yeon. There is lots of blood, as sickening realism is a main selling point of this film, unlike any other you have seen.

Ju-yeon was on the way home when she has a flat tire in a remote area. A man stops and offers help, but she refuses as she is on the cell phone with Lee. However, the man comes back, smashes the window and savagely attacks her before dragging her off to his secret hideaway, where he kills her after she begs for her life. Ju-yeon also was the daughter of a retired police chief and he is given the dossiers on four possible suspects. He turns the files over to Lee, who violently attacks the first two on the list, before hitting pay dirt with the third, Kyung-chul (Choi). Lee finds where Kyung-chul kills his victims and Ju-yeon’s engagement ring. Fifty minutes in, Lee finally catches the killer, sparing another victim accidentally in the process, and then the film turns very interesting. Instead of turning Kyung-chul over to the police, he beats him, plants a tracker on him and then leaves. For the rest of the film, they play a deadly cat-and-mouse game of increasing violence, as Lee keeps interrupting Kyung-chul’s evil work and further maims him. However, there is a price to pay, both in Lee’s turning into a monster himself and the at least three deaths and three major injuries Kyung-chul is allowed to commit by not having been brought to justice immediately.

This is not a film for the faint of heart, but it is a riveting journey, as were “Silence of the Lambs” and “Se7en.” Kyung-chul even has a friend who is a practicing cannibal! The Blu-ray DVD includes 11 deleted scenes (24:50), including an extended ending that hints Lee will not give up his search for other monsters. There also is 27:06 of behind-the-scenes raw footage. Grade: film 3.5 stars; extras 2.5 stars

Black Death (Magnet/Magnolia, Blu-ray or standard DVD, R, 102 min.). This is another film in which the “good guys” turn out to be evil as well. Sean Bean plays Ulric, an envoy to the Bishop who is tasked to find a remote village that may be led by a necromancer, as it is untouched by the Bubonic Plague that currently is ravaging Europe (the year is 1348 and the Black Death will claim 50 percent of the population). Assigned to help him find the village is Osmund, a novice monk played by Eddie Redmayne. However, Osmund is conflicted because he meets frequently with a childhood friend (Kimberley Nixon as Averill), with whom he is in love. He sends her to safety but when he reaches their planned meeting place she appears to have been killed in an attack.

While poised between occult thriller and action film, director Christopher Smith actually examines the subjectivity of blind faith and its attendant brutality. One battle sequence in particular is quite brutal. However, the film’s reveal comes about an hour in and then it really has nowhere to go, and ultimately disappoints. David Warner plays the Abbott and the village is run by Hob (Tim McInnerny) and Langiva (Carice van Houten). Extras include four deleted scenes (4:22) that add nothing; an 11:35 making-of featurette; 12 interviews with cast and crew members (32:36); and 10:42 of behind-the-scenes footage. Grade: film and extras: 2.5 stars
