Hey Mark,
Watching it twice wouldn't have anything to do with fellow Brit Jenson Button winning his first F1 race, would it?

The rain did play havoc on the teams tire choices and the drivers ability to keep the car from spinning. Bridgestone certainly got smoked in the tire wars for wet conditions. The Hungaroring always seems to produce something unusual, and seeing Honda win was certainly out of the ordinary. They've had a pretty miserable season up to that point.
As far as the F1 regualtions goes, I'd hate to see them turn into another NASCAR. Formula One has always been about cars with cutting edge technology.
