The first time Russell T Davies helmed the Doctor Who series, his run was a triumph of stories and characters that reinvigorated a franchise previously thought "dead." Whereas his initial outing as showrunner was all about the "new," this time he's brought back a little of the "old," specifically David Tennant's version of the Doctor. More importantly, however, he restored one of the Doctor's greatest companions, Donna Noble, from the regrettable status quo he left her in. This is good news for fans of that Doctor Who era and promises a bright future for Donna and her daughter Rose Noble.
