I don't know... IMO, it was too self absorbed, too convoluted even for Dr Who, in danger of losing it's 'target' audience - while also appealing to adults, didn't like the writing, not convinced by the series or this episode. Matt Smith is no David Tennant, and bring back episodes like the Empty Child, Sally Sparrow, and the Girl in the fireplace...
Not saying it wasn't worth watching though...
and... the Rory character was on-balance probably a mistake, as it IMO adds an unwanted plot dynamic detracting from the Doctor - companion relationship, a feature over the years.
