Predictions for the Moffat tenure
1. A lesbian companion.
2. Considerably reduced representation of our homosexualist brethren otherwise.
3. A male companion in the Fitz Kreiner mould lusting after the female companion.
4. Comedian Harry Hill used to tell a joke, like "Dogs should only eat things that their breed rhymes with, so a poodle could only eat noodle and strudel. But unfortunately that is the only dog that rhymes with a type of food." and then revisit it later in his routine. But once he had his own series, this structure was expanded to jokes that would be revisited weeks after they were initiated. I therefore predict a timey wimey subplot strung through the whole of series five: something just slightly more complex than the simple circular logic of Time Crash or the MacGuffin in Mawdryn Undead, something more like the 8th doctor novel "Vanderdeken's Children".
5. Seriously, stop trying to think about it: that is the only dog that rhymes with food.
6. Really explicit reference to the Talons of Weng Chiang rather than all this hooing and hahing about clockwork robots and time agents. With Jimmy Vee as Mr Sin.
7. Something clever with the TARDIS translation circuits, leading to a story from different viewpoints.
8. After two stories (Blink and Time Crash) featured near word-perfect reinterpretations of scenes from the Red Dwarf episode "Future Echoes", I anticipate another Red Dwarfalike with potential for cleverness, such as reinterpreting "Backwards".
9. No supporting cast of families; maybe some "UNIT family", but no reoccurring friends and family of the companions: maybe a return to the tradition of killing off Aunt Vanessa in their debut, or the return of the uncontrollable TARDIS. Golden Labrador, Lobster Thermidor: you can have that one.
10. Less of the "Cult of the Producer": you never saw Philip Hinchcliffe on Doctor Who Confidential in 1975 did you? Not in daylight, anyway. I propose that Sir Steven of Moffat will not be seen commenting on any story he did not write, with the resultant decrease in fandom's "Oh Rusty, *rolls eyes*" near-fetishistic attribution of all good and ill to a single individual (with the exception of continuing to blame Murray Gold for the sound).
