I never read any genuine negativity in Peter Davison's comments. He began the sentence, "
If I feel any doubts..." Overall, he seemed positive to the idea. But, once again, the Left eats one of their own simply for expressing nuance. (And congratulations to Colin Baker for finally becoming more popular than Peter Davison!

)
BTW, I wonder how some of the more romantically-tinged companions like Rose, Martha, or even Jo (albeit in a more platonic-crush sort of way) would react when meeting the 13th Doctor?
