In the grand scheme of theological thrillers; Constantine aspires for the greatness of The Exorcist but ranks more closely with The Order. Based on the popular Hellblazer comic book series; and directed with nary a shred of intelligence by music video veteran Francis Lawrence; it's basically The Matrix with swarming demons instead of swarming machines. Keanu Reeves slightly modifies his Matrix persona as John Constantine; who roams the dark-spots of Los Angeles looking for good-evil; angel-devil half-breeds to ensure that "the balance" between God and Satan is properly maintained. An ancient artifact and the detective twin of a woman who committed evil-induced suicide (Rachel Weisz) factor into the plot; which is taken so seriously that you'll want to stand up and cheer when Tilda Swinton swoops down as the cross-dressing angel Gabriel and turns this silliness into the camp-fest it really is. The digital effects are way cool (dig those hellspawn with the tops of their heads lopped off!); so if you don't mind a juvenile lesson in pseudo-Catholic salvation; Constantine is just the movie for you! --Jeff Shannon
