Rolling Stone says, "No movie in the last year is more redolent of sorrowful beauty and exhilarating action." Roger Ebert likes it. Slant Magazine does not. Salon.com has a review here. Christianity Today explores its Christian connections. The Guardian calls it "an excellent thriller" and says, "Cuarón has created the thinking person's action movie." EW says it's "Thrilling, important, and invigoratingly bleak". Moria says,
Children of Men is a strong and intelligent venture into the dystopian future theme, a mini-genre that has waned somewhat in recent years. Children of Men could easily be a throwback to 1970s dystopian films set in infertile/breeding-restricted futures...
Slate's reviewer describes it as "a modern-day nativity story" and predicts,
Children of Men (Universal), Alfonso Cuarón's dense, dark, and layered meditation on fertility, technology, immigration, war, love, and life itself may be the movie of the still-young millennium. And I don't just mean it's one of the best movies of the past six years. Children of Men, based on the 1992 novel by P.D. James, is the movie of the millennium because it's about our millennium, with its fractured, fearful politics and random bursts of violence and terror.The New York Times calls it a "superbly directed political thriller," saying it
may be something of a bummer, but it’s the kind of glorious bummer that lifts you to the rafters, transporting you with the greatness of its filmmaking.
