I'm giving it a big old fat 8.
Really enjoyed that one with some great moves and battles. RoGro vs Hamilton; Hulkneberg vs Alonso; Hulkenberg vs Hamilton; Hamilton vs Alonso - all clean, fair and very exciting.
Not to mention 5 abreast on the first lap and that massive scrap with Maldonado, Gutierrez, Massa, Sutil and Bottas!
It was a master class from Vettel again but Grosjean at least kept him honest this time and within 5 - 10 seconds and it was a shame he ended up being jumped by Kimi after the safety cars.
Really enjoyed that one.
