Vettel is actually a superb driver!!!
There are lots of opinions on this BUT you can't argue with results. He is in a top 'car' but you can't become World Champion unless you are.
The problem IMO is that modern 'PC correctness' means that these guys appear boring and characterless. Also the cars are so reliable that if the driver sets a Pole lap they are half way there.
The 'characters' of this world are being subdued in all walks of life because life can be so predictable and controlled now. I know from living with my grandfather for 5 years (he died at 98) and listening to his stories of the first world war and also from my dad who is now 92 (and a WW2 veteran) and so interesting to talk to, that we are missing out somewhere. The hardships and camaraderie built characters.
I've rambled on to make my point I know but Vettel (like Loeb and Shumacher) is exceptional! It's a shame that in certain eyes it is seen as boring. They can win multiple championships because the team support can be reproduced in a modern world, that is the boring and predictable bit, not the driver..
