I've gone for a little, because rarity pushes up the value.
Think back 3-and-a-bit weeks, to the Chinese Grand Prix. Lewis Hamilton passed Jenson Button down into Turn 1, outside the DRS zone and on the same tyres. That brought him to the head of the three stopper queue and he went on to win the Grand Prix by passing the two guys in front. I presume few here were disappointed.
Now Turkey had a less satisfactory conclusion. The three podium finishers were a long way clear of the action, and there was not a real Grand Prix deciding moment. There were 126 overtakes, but many were not seen and those that were generally saw Nico Rosberg falling down the order or something that was overturned by a pit stop.
No set of rules will create a Grand Prix like China every week. They can't create a situation where the leader may always be under threat, especially if he's a half second clear in qualifying. But the reason the Turkish GP did not satisfy as the Chinese GP did was not DRS, nor Pirelli, nor KERS. Simply, the overtakes seemed irrelevant; they seemed not to affect the result, and that led to the empty feeling that accompanied the end of the race.
