I'm on the side of having characters who act in character on a consistent basis, rather than acting any which way because it suits the demands of a plot.

Me, too.

I know people moaned that Rusty was crap at making plots make sense - and there are times when I can certainly agree with that - but there's been this "Emperor's New Clothes" attitude towards Moffat in some areas of fandom, as if he's not guilty of the same thing sometimes.

I said when I watched Sherlock earlier this year that I felt that THAT was the DW that Moffat really wants to write, because to my mind, Eleven's seeming lack of concern for the other frozen IOUs would have fitted Sherlock Holmes perfectly.

And yeah, I'm the Doctor and I cured them! might make me wince... but at least Ten's hearts were in the right place!
