Do you consider Cecilia Bartoli to be talentless?

Many artists - not just singers but instrumental musicians and conductors too - have faults and annoying mannerisms, Of course Bartoli isn't talentless (you know that!) and I find her minor foibles far less annoying than those of, say, Maria Callas, who I can't actually listen to for more than a few minutes. The grainy tone and harshness of her voice grates on me far more than anything Bartoli throws at me.
