Yup... agree with you Bill, on the "creepy" factor. Creepy and tragic.

I think Asylum's storyline was a great one indeed, from this point of view.

...and I think it explores the hypocrisy that always seeps around the edges of their xenophobia too... hopefully that's a reasonable way of wording what I'm trying to say.

I like the "Revelation of the Daleks" storyline for similar reasons.
