The Most Interesting season in F1?

The season sees the return of the Legend (Schumacher), the Legend Killer (Alonso), the youngest (Hamilton) and the unlikeliest (Button) champions all facing off. So, this promises to be most interesting season yet, right? I doubt it. it simply means the title will go to one of them. Or to be more precise, any one of them except Button. Ferrari, McLaren and Mercedes have all tweaked their cars to ensure lightning does not strike twice. If its the most interesting season in F1 you're looking for, then all you have to do is go back into time to January till late 2009. Now THAT was some season.
