It's a hard one this, if only because I think it's my earliest memory, just before getting Pokemon Blue. Anyway, point being, I don't actually know. I remember Daleks, of many colours. A red one is pushed down a pit of some kind. There's these wooden buildings, and trees all around them. It's probably in a quarry. Which Doctor/Episode/Film is this? Damned if I know, but I'm certain it was my first.
Later (much, much later) on in life, I managed to catch the final episode of Eccleston's Doctor as it played out on TV. I was kinda amazed by it all, although that was partially by the absurd body count that episode has. I've pretty much seen every one ever since then.
