How would the modern face of policing cope in the land of The Sweeney? That's the question posed by Life on Mars, as DI Sam Tyler (John Simm) a modern cop transported back to 1973 after a nasty car accident. There, he finds himself dealing with the significantly rougher attitudes and behaviours of "old-school" British policing, as exemplified by his new boss, DCI Gene Hunt (Philip Glenister). It's a fish-out-of-water story, as Tyler attempts to teach his new colleagues some very modern methods, while attempting to get used to sheepskin jackets, wide lapels and man-made fibres. This first series of the hugely successful BBC programme sets the scene and introduces the characters that make up Tyler's new world, but stumbles a bit by trying too hard to explain exactly how he got there (the "coma" subplot just gets in the way). Life on Mars is at its best when Glenister is on screen--he's bigoted, chauvinistic and aggressive, and goes through each episode alternately bellowing or scowling. But he's a product of his times, and in his heart, all he wants is to catch the bad guys. For Tyler, it's all about the means, while for Hunt it's all about the ends. They may not like each other much, but their on-screen chemistry is undeniable, and just one of the things that make this excellent series so watchable. --Ted Kord
