There's not one cougar to be found in 24's dynamic third season, and that's good news for everyone. After Jack Bauer's daughter Kim (Elisha Cuthbert) survived hokey hazards in season 2, she's now a full-time staffer at CTU, the L. A. -based intelligence beehive that's abuzz once again-three years after the events of "Day Two"-when a vengeful terrorist threatens to release a lethal virus that could wipe out much of the country's population. Jack (Kiefer Sutherland) attempts to broker a deal for the virus involving drug kingpin Ramon Salazar (Joaquim de Almeida), whose operation Jack successfully infiltrated at high personal cost: to maintain his cover, he got hooked on heroin. That potentially deadly triangle-drug lords, addiction, and bioterrorism on a massive scale-sets the 24-hour clock ticking in a tight, action-packed plot involving a potential traitor in CTU's midst; the return of TV's greatest villainesses in Nina Meyers (Sarah Clarke) and former First Lady Sherry Palmer (Penny Johnson Jerald); a troubled romance between Kim and Jack's new partner Chase (James Badge Dale); and a scandalized reelection campaign by president David Palmer (Dennis Haysbert), who monitors CTU as they struggle to (literally) save the day. The intricately woven subplots that are 24's greatest strength are masterfully developed here, and character arcs are equally strong, especially among CTU staffers Tony (Carlos Bernard) and his wife Michelle (Reiko Aylesworth); CTU director Ryan Chappelle (Paul Schulze), who is season 2's tragic bargaining chip; and the annoying but well-intentioned Chloe O'Brian (Mary Lynn Rajskub), who makes pivotal contributions with by-the-book efficiency. It's 24's superior casting that overcomes the series' occasional lapses in credibility, and season 3's twists make marathon viewing a nerve-wracking delight. By the time it's all over, with a high body count and the surgical reattachment of a main character's severed hand, 24 once again leaves you gratefully exhausted. As always, Sutherland anchors the series in the role he was born to play. [+]

The further adventures of Los Angeles' Counter Terrorism Unit's finest initially sees Kiefer Sutherland's Jack Bauer in a Chinese prison and not in good shape. But, this being 24, it's not too long before the breakneck plot has revved into gear, and the wheels are turning again on a frantic real-time ride that's thoroughly in the tradition of what's become television's finest thriller. You won't be finding plot spoilers here, because half the fun of 24 is not knowing what unexpected twist the scriptwriters have for you around the next corner. All that matters is that the world is under threat, and it's up to Jack Bauer to lead the fightback. And it's Kiefer Sutherland that's the real asset to series six; whereas particularly in season five he took a sideways step to accommodate stronger supporting characters, here he's shouldering a greater degree of the show's narrative thrust. You'd be hard pushed to declare that season six is vintage 24, but that's more to do with the context of particularly the excellent run that preceded it. But few shows can match its audacious verve, and repeated ability to surprise and enthral. So while season six may have too many villains, and may ask you to bear with it through a few troughs, there's still nothing out there to match it. Jump aboard… -Jon Foster.

Jack Bauer is having another one of his "very bad days" in the second series of the ground-breaking real-time thriller 24. Once again the hours are ticking by with more guaranteed cliffhangers than a convention of mountain climbers. Holed up in a Los Angeles condo and estranged from his daughter, Jack is no longer on the government payroll; unfortunately for him, this small fact doesn't seem to matter to President David Palmer and the NSA who call him back in to the CTU and give him 24 hours to infiltrate a terrorist organisation who are planning to detonate a dirty bomb in the city of angels. All Jack wants is to get his daughter out of the city, unfortunately Kim's new employer, the abusive father of the child she is nannying, has other ideas. Fans of the original won't be disappointed, as there are more than enough shock moments in the first few hours to hint at the climactic build-up to come, while newcomers can quickly get involved in the lives of Jack and his family. There are some new characters to bolster the veteran cast and, interestingly (although not surprisingly given the outcome of the first series), Jack's character has taken an altogether darker, more psychopathic turn. The danger the characters find themselves in also has a much more global impetus, grounded as it is in the war against terrorism. Although the territory is more familiar this time around, this second series is just as much a high-tension, taut, adrenaline-fuelled ride as the first series, and one that will have you glued to your TV for the next 24 hours. -Kristen Bowditch.

Such a simple idea-yet so fiendishly complex in the execution. 24, as surely everyone knows by now, is a thriller that takes place over 24 hours, midnight to midnight, in 24 one-hour episodes (well, 45-minute episodes if you extract the ad breaks). Everything to take place in real time-on-screen and off-screen time the same-which means no flash-backs, no flash-forwards, no nice handy time-dissolves. Every strand of the plot has to be dovetailed and interlocked to make sure that things happen just when they should, in the right amount of time. Not that easy. Creator Robert Cochran and his team of writers and directors have done a pretty impressive job in putting the jigsaw together and keeping the tension ratcheted up high, as Federal Agent Jack Bauer (Kiefer Sutherland) hares around LA trying to stall an assassination attempt on a black Presidential candidate and rescue his wife and daughter from the clutches of the Balkan baddies. Twists, turns, revelations and cliffhangers are tossed at us with satisfying regularity. It's not perfect: we get some hokey plot devices (instant amnesia, anybody?) and the final twist, once you start thinking back, makes no sense whatsoever. There are altogether too many huggy family moments ("I love you, Dad. " "I love you, son"); and as for überbaddie Dennis Hopper's "Serbian" accent… Even so, this is undeniably mould-breaking TV. [+]

The adventures of Counter Terrorism Unit agent Jack Bauer have rarely been dull. Yet after four series of battling the bad guys in real time, some could rightfully wonder whether 24 had lots its edge, and its ability to surprise. The fifth season should put any such doubts to shame. Set eighteen months after the dramatic finale to Season Four, things get off to a shocking and pulsating beginning. You won't find plot spoilers in this review, yet it's as if the writers realised they had some serious carpet-pulling to do to keep the show's audience intrigued once again. Set, as usual, over the course of one single day, there's then a slight lull in the first third, before things spring ferociously into life. Make no mistake: if you can overcome the usual need to suspend elements of your disbelief, this is the best series of 24 since the first, and as it winds near to its equally dramatic conclusions, it's simply hard to take your eyes off it. Joining the usual cast too is a procession of familiar names. Peter Weller (Roboocop), Sean Astin (The Lord Of The Rings) and C Thomas Howell (The Hitcher) are among those doing their curriculum vitae no harm, but the acting honours are taken by the wonderful combination of President Logan and his first lady, played by Gregory Itzin and Jean Smart. With a denouement that sets up a sparkling sixth season, this fifth series of 24 is a genuinely significant achievement. [+]

Hard to believe, but after all these years, 24 is as vital and compulsive as it always was. For this fourth series, the rules are still the same: all the action takes place in real time, and the series again follows a single day in the life of Jack Bauer (Kiefer Sutherland). Fortunately, Jack's knack of attracting trouble hasn't deserted him either, and quickly, it's business as usual. Starting the series with a fresh romance, a different job and one heck of an explosion, it doesn't take long before Jack is back in action, and he's soon joined by a mixture of new and familiar faces. To talk about the plot would be unfair, as 24 is consistently a dish best served cold. Suffice to say that there's a heady mix of plotlines, twists and downright brilliant cliffhangers. Perhaps the cocktail isn't as fresh as it once was, and there are moments where you can't help but feel that plausibility is being stretched a little too far. But accepting that is part and parcel of the 24 experience, and arguably part of the fun. That's because even as it approaches its final stages, 24: Series 4 maintains a tremendous momentum and level of intrigue, and by the time the clock ticks for the last time at the end of the 24th episode, odds are you'll be thirsting for more. Bluntly, in spite of its flaws, 24 remains one of the most essential shows currently on television-and this series offers ample evidence why. [+]
