Australia always has a certain frisson to it, because it's the start of the season, when all the BS stops. And it's a real effort to watch it live (it's on really early here). Monaco is often really exciting, even though it flatters to deceive, because it's so hard to pass. And Bahrain and Hockenheim produced interesting races in '04, in spite of their Tilke origins.
Most of all though, I hope that Ferrari are pushed. Watching the live timings last year was depressing. I knew right from the first round that Ferrari would be virtually unbeatable, simply by watching the race lap times.
