I'm sure you're right. Sometimes I feel like fansom thinks any and all female characters are Mary Sues. And noone is ever happy. It's the endless complaining - too young, too old, too pretty, not pretty enough, too naive, overconfident and so on. All Mary Sues. And annoying.

I liked Canton but I generally like Mark Sheppard and his characters, especially the ambiguous ones and they played right into it at the beginning of second episode. Still I love River more. And I loved all Moffat's female characters so far and I hope he will make more. Recurring. Till fandom just collapses from massive stroke.

It also reminds me of the comparisons between Jack and River and the fandom reaction to them. The whole thing almost made me feel weird for liking both.

Although I think fandom liked Sally Sparrow but I may misremember. Too bad she won't come back.
