When he did that in Father's Day, I honestly thought it was kind of off and I'm glad they didn't bring that back.

The trouble with introducing TARDIS ex machina is that once it's there, it's canon and you're stuck with it. I thought that the homing TARDIS makes things a little too easy, too, but they've done it now. The annoying thing is that the plot of Father's Day could easily have been made to work without it.
