The thing about River intrigues me. With the whole bit about rewriting time, does that mean the Vashti Nerada thing doesn't happen anymore? Or what is the deal with her killing someone important (if it's the doctor, how come he is still alive before Silence in the library?)

I've seen some comments about people complaining that This season seems too Final Fantasy/Fairy Tale-like, but I dunno, that's what I liked about it anyway.
