Seeing as I’ve only been a Whovian for about three years now, I can only imagine what a long time Whovian’s reaction was when they watched this back in 2005. I’d imagine that they wouldn’t be quite sure what it was for until the TARDIS console was shown, and then they probably definitely knew what it was when the *Doo-weee-ooooo* played, along with the Dalek. I can then imagine them overflowing with excitement and joy.
