30 Days of Doctor Who: Question 21: Favourite setting..
Dr. Henry Van Statten's underground hoard of artifacts from series 1, episode 6, "Dalek".
I loved that episode. I thought Dr. Henry Van Statten was one of the better villains, and I loved the idea of his mysterious American underground bunker of high-tech memorabilia, oddities an aliens.

I really, really wanted Dr. Henry Van Statten and his collection to crop up in an episode of Torchwood, or even just to be mentioned, but it never happened.
