Re: Strax, Jenny and Vastra (and to a lesser extent River)
I could go with at least one more River story. I keep thinking that after all the times we've seen her, we still don't know anythign about what makes her tick. I keep hoping she'll get that one good story where we'll finally get a chance to see just what the Doctor sees in her. It would actually be interesting to have her meet a Doctor that she can't fluster.
As for Vastra and the others, they're characters I don't see myself ever getting tired of.
