I don't think, given the conclusion of that race, that I can award it any more than a 3.
OK, we had a straight fight between the Mercedes, there was a great performance from Button and some excellent overtaking at Red Bull. There were some other negatives, the inconsistency of Safety Car deployment, the farce of the first two laps and Alonso losing his chance in such an anti-climactic way.
I doubt the 2014 Japanese Grand Prix will be one we can look back to with any fondness though, so 3.
