Thank you Steven Moffat ...

... for coming up with a 50th anniversary episode that worked, one that managed to do homage to the history of Doctor Who without becoming bogged down in it, one that resolved old plotlines and then headed off in a new direction, one that managed to both work within the parameters set by the show's previous canon and also reconstruct them to produce something unexpected but fitting.

In short, thank you for producing a beautifully fannish piece of work.
