No offense to the Who team, but "Confidential" ranks - to me - way below Torchwoord, and Sarah Jane Adventures (RIP Elizabeth Sladen), for spin-offs I would like to see return.
It also ranks below the spin-offs we never got for The Doctors Daughter, Clara and Me, Ianto, Martha Jones, Micky and the Anti-Cyberman Defense Force, Teagan and Jo Grant at Unit, and about half a dozen Big Finish properties.
...
All that said, I am pleased to see confidential return.
