I always gravitate back to the human nature/family of blood Doctor Who episodes. Something extra awesome/touching about them that really resonates with me. Course then I have to watch The End of Time for the sweet call back. It’s my Who vicious circle.
PS. I love when Tennant regenerates he fucking takes the Tardis with him. It’s the Who equivalent to just dropping the mike. “Tennant…….OUT!” *THUD!……feedback noise*
