Whether you like or inexplicably loathe Russell T. Davies, you have to admit that the man expanded the world of Doctor Who, working to fill it with a roster of unforgettable side characters like Rose, Jackie Tyler, River Song, The Doctor Donna, Wilfred Mott, Mickey, Martha Jones, and Captain Jack. Davies didn’t just let these characters roam though, he serviced them and made us care and even long for their return appearances.

Doctor Who, in the time of Steven Moffat, has not similarly excelled in this area. Oh sure, the love story of Rory and Amy will be written in the stars and spoken about for the whole of time (or something), and Moffat has more fully realized (for better or worse) River Song, his creation, but they don’t seem right for a spin-off and for the most part we only get snippets of other, smaller characters who we would love to get to know more.
