Life in Cold Blood, 7.30pm, Nine
Ancient king of the naturalists David Attenborough continues his series about cold- blooded animals with an episode entitled Dragons of the Dry . It concerns the remarkable journey of those amphibians that left the water and just kept going, dispensing with the need to return to mate and breed. Stunning photography and an even- handed presentation add up to compelling entertainment.
SCU: Serious Crash Unit, 8pm, Seven
Desperate Housewives, 8.30pm, Seven
Cars collide with trees in New Zealand. Imagine. Constables Karl Bevin and Blair Atkinson of the Waitemata District Serious Crash Unit are collecting evidence about a car that did just that in Auckland, killing an occupant. With less drama and mystery than watching the paint dry on a Kare Kare beach house, the time plods by. If you are still conscious by program’s end, you can find out what went wrong. In the wake of any great disaster, people, even the incredibly selfinvolved narcissists of Wisteria Lane, start to perform small acts of kindness. But small acts of kindness, including the decision on the part of the writers to spare the regulars from the ravages of a tornado, and Susan’s reluctant acceptance of the now homeless Bree ( Marcia Cross, pictured), are dwarfed by a revealed act of heroism and sacrifice. Naturally, hardly anyone notices. Later, Bree pimps her son to the gay roofer so she can get her house fixed and move back home. ‘‘ You can raise a man’s hopes without satisfying them. I’ve done it all my life,’’ she tells him.
