God forbid they write stories that require more plot than CGI then.

Nastily, I wonder if this is one of the reasons Rusty's moving on, because he does tend to hinge his plots on spectacle rather than storyline. Considering that Moffat made two nations wet themselves with terror over a 5-year-old in a gas mask calling for his mother, I have confidence that he will be able work within budgetary limitations so well the audience won't notice.
