This diluted but visually arresting adaptation of the comic book Hellblazer stars Keanu Reeves as chain-smoking John Constantine, a cancer-ridden exorcist who's condemned to save souls and take on all manner of vile demons on Earth. Rachel Weisz co-stars as a police detective who teams up with Constantine after her apparently deranged twin sister (also played by Weisz) takes a swan dive off a high ledge. Much muttering follows about portals between heaven and Earth, the struggle between good and evil, and there's some silliness involving a relic that's found in the Mexican desert wrapped in a Nazi flag. Ultimately, the script feels like little more than sticky tape holding together the visual effects, but they're very impressive effects indeed, indicating that former pop-video director Francis Lawrence definitely has an eye, if not yet a lick of storytelling sense. And Tilda Swinton is utterly delicious as an androgynous angel.

John Constantine has literally been to Hell and back. When he teams up with a policewoman to solve the mysterious suicide of her twin sister, their investigation takes them through the world of demons and angels that exists beneath the landscape of contemporary Los Angeles.
