Dominion: a Moderate Defense of the Film
Dominion is the slower film, but it still beats out Beginning. Why? Because its theme(s) are more serious and its horror(s) more nuanced. Just contrast the DVD cover art. Beginning features a "scary" demonic face. Dominion features Merrin reverently kissing his Rosary. The respective covers eloquently express the difference between the two films.
Dominion has none of the sexual crudity of Beginning (Scorupco's "impossible" vaginal bleeding, the British alcoholic's nasty remarks, no "I'm gonna f--k your juicy ass"), no incredibly huge battlefield of upside-down crucifixion victims, no dreamscape of mutilated bodies, no "erotic" wrestling match between Skarsgaard and Scorupco ... etc. Also lacking is Beginning's puerile, Hollywoodesque theory that "Satan fell from heaven on this spot!" gibberish.
Dominion's theme is Merrin's re-conversion to Catholicism/priesthood. In Beginning this theme is present, but overshadowed by the gore and sfx. When Merrin kisses his Rosary in Dominion, the film delivers its thematic core with no frills. Its exorcism - which according to Blatty, "damn near killed" Merrin - is stressful but not lethal. However, contrasted to the Skarsgaard-Scorupco grope, Dominion's exorcism scene is pure art.
Nuggets do not abound, but a few are at least present, as when Fr Francis angrily chides Merrin for condemning in others a hope he himself once gave his life to; when Francis expresses horror at the human sacrifice evidence found in the temple's "satanic" understructure, and Merrin caustically says, "Reminds you of the Holy Inquisition"; when Merrin and the Nazi-tortured nurse are discussing evil, and Merrin confesses: "I chose good. Evil happened" and the nurse replies in a strikingly Blattian line: "Sometimes I think the best view of God is from Hell." Good stuff. Not enough of it, but still good stuff.
Neither film, of course, was classic cinema. It's just that for me, Dominion is the lesser of two evils, and contains a few dramatic and theological nuggets to boot.
