The pilot episode received a rating of 11.1 from Nielsen Media Research on January 13, 2008. The mainstream press reviews were generally positive. USA Today gave the premiere episode 3 and a half stars out of four, calling the series, "smart, tough and entertaining." The New York Times referred to it as "one of the more humanizing adventures in science fiction to arrive in quite a while", while the Los Angeles Times declared the show "has heart and feeling" and "an almost Shakespearean exploration of fate vs. character" that features "plenty of really great fight scenes, and explosions, as well as neat devices developed in the Future and jury-rigged in the present." In addition, film industry journal Daily Variety declared the series pilot "a slick brand extension off this profitable assembly line" that showcases "impressive and abundant action with realistic visual effects and, frankly, plenty of eye candy between Glau and Headey." At the start of the second season, Variety praised "Headey's gritty performance as Sarah — managing to be smart, resourceful and tough, yet melancholy and vulnerable as well" and that the Chronicles "continue to deliver", getting "considerable mileage out of the constant peril" facing the characters. The Connecticut Post placed it on its list of the top 10 TV shows of 2008: "It's smart, with thought-provoking meditations on parenthood, destiny and human nature, and features good performances by Lena Headey, as Sarah, and Summer Glau."
