"Top Gear: The Complete Season 10 / Clarkson: Heaven And Hell" - If you thought "Top Gear" might calm down a bit and the presenters would start to act their age, well, you're wrong. Season 10 is one of the most ambitious yet, featuring some challenges that only the very brave - or the very stupid - would dare to undertake. For example, who in their right mind would attempt to drive through the Kalahari Desert in three 20-year-old bangers? Or try to cross the treacherous English Channel in a fleet of amphibious cars that are less seaworthy than the average church? You guessed it - "Top Gear's" three intrepid presenters Jeremy Clarkson, Richard Hammond and James May! But "Top Gear" is much more than just three grown men - who should know better - larking about. There is some serious car journalism in here too, with exhaustive road test of the latest models, a search for the perfect driving road in the Porsche 911 GT3 RS, Lambo Gallardo Superleggera and Aston Vantage N24, a look-back at the history of motoring, man versus machine experiments, and power tests featuring the world's most exotic supercars, including the Ferrari 599, Audi R8 and Caparo T1. And, of course, all the tried and tested "Top Gear" favorites makes a welcome return including "the news"; the 'cool wall' and The Stig, who put the rich and famous through their paces in the regular "Star in the Reasonably Priced Car" feature. "Clarkson: Heaven And Hell": I trawl the whole of cardom to bring you seven great cars and truffle the undergrowth looking for seven automotive disasters. The good ones - the Ferraris, the Porsches and the Aston Martins are driven to within an inch of their lives on the track. Some are even handed over to the Stig who makes a guest appearance. The bad ones are killed. Sawn in half. Hung, drawn and quartered. They're hammered and blown to pieces with dynamite and their skeletons left in the open to rot. I even find time for a game of car jousting. It's "Heaven and Hell". Enjoy.
