A toss up between 8 or 9 - went for a 9 in the end.
It had all the appearances of 'proper racing' - maybe induced by the lack of Marussia and Caterham; the camera work and broadcast direction was better than usual which gave an accurate sense of the rise and fall of the track, the corner cambers, and included a lot of overtaking (I think).
Sorry for Danny Smiler; happy for Nico, Lewis and Mercedes. Plus Massa and Button.
Downside were the pit crew errors, they must all be getting tired now!!
