The real problem here as I see it for a lot of fans is that the miami gp was hammed up to puke inducing levels while at the same time producing a competition of no real fight. It really should be none championship with noddy cars or something.
The other very real problem is that a lot of fans really don't like redbull and Max, particularly since the AD debacle which was not their fault.
Finally the rest of the teams also seem to be incapable of producing a car to match the redbull and are now giving the appearance of being incompetent clowns. This leads me to one of two conclusions, either all the other teams bar those plucky guys at AM are indeed incompetent engineering teams or redbull are doing something significantly different that no one has any idea about.
Everyone keeps harking back to the merc years of dominance and that did indeed kill the show, but the reason was fairly clear, Merc had by far the best engine package. The current redbull advantage just cannot be pinned down, certainly not by the layman.
Personally I think ferrari are a good example along with maybe maclaren, they have produced beautiful cars, their engineering teams appeared to understand the new regs last year, but this year far from taking a step forward they both seemed to have moved backwards.
So pragmatically the redbull achievement just doesn't make logical sense at the moment. There is something else going on, it must be legal because even the fia can't be that stupid, but it is not insignificant.
As for merc, they really have ended up in a management meeting style death spiral, hopefully the imola upgrades will do something but I'll believe it when I see it.
