Creating and executing a TV series in which each season takes place in the course of just one day, with each episode occupying a single hour, is no mean feat, but the makers of "24" have pulled it off admirably. And while many of the show's longtime adherents seem to agree that this sixth season (with 24 episodes offered on six DVDs, plus a seventh disc loaded with bonus features) is perhaps its weakest, relative newcomers, freed from the expectations generated by the five that preceded it, will find it to be riveting entertainment. This is a show that hits the ground running and then proceeds to relentlessly ratchet up the tension, balancing its disparate elements--terrorism and espionage, political intrigue and treachery, personal drama--with remarkable aplomb. Indeed, the first episode is barely underway before we're told that a plague of terrorist bombings is sweeping the United States, killing many hundreds and leaving the nation in disarray. President Wayne Palmer (DB Woodside), in office for just three months following the assassination of his brother, agonizes over the proper course of action while some of his advisers counsel restraint and others urge him to adopt measures that will radically restrict Americans' (especially those of Muslim descent) civil liberties. Meanwhile, Jack Bauer (star and executive producer Kiefer Sutherland) has been released after two years in a Chinese prison, but only so he can be handed over to Abu Fayed (Adoni Maropis), a particularly nasty villain who proposes to trade Jack's life for the location of Hamri Al-Assad (Alexander Siddig), who's suspected of being the mastermind behind the current reign of terror. That's only the beginning, of course. Soon Jack (who, despite being severely tortured during his imprisonment, is still cool enough to coordinate a manhunt while simultaneously disarming a bomb set to detonate in two minutes) and his counter-terrorism cronies are dealing with the specter of a nuclear holocaust on American soil, more political assassination, Jack's feckless family, and a good deal more. And that's only in the first twelve hours! It doesn't all work--especially in the second half. Some of the characters are less than convincing (Jack's brother Graem, portrayed by Paul McCrane, is weak in every respect; in fact, the entire family sideshow is fairly ridiculous), while the casting is sometimes off the mark (Woodside does his best, but he lacks the gravitas needed in a plausible Chief Executive) and the story contains multiple plot points that will challenge even those willing to totally suspend their disbelief. By and large, though, "24" more than lives up to its own hype as the tube's most addictive program. Bonus material includes commentary on selected episodes, deleted scenes, a preview of Season 7, several featurettes, and a whole lot more. "--Sam Graham"
