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. Sutherland, rescuing his career from the doldrums in one heroic leap, fully deserves his Golden Globe. Sets and locations are artfully deployed--we gain a real sense of LA’s splayed-out geography--and Sean Callery’s score is a powerful, brooding presence. Like Murder One and The Sopranos, 24 is one of those series future TV thrillers will have to measure themselves against.

On the DVDs: 24 is released in a six-disc box set. On discs 1- 5 there are no extras, but disc 6 includes the "alternative" ending and a preview of Series 2, presented by an urbane Kiefer Sutherland, that tells us precisely nothing. The transfer, in 16x9 widescreen and 2.0 Dolby Digital sound, does the high production values of the original every justice.--Philip Kemp
