I actually got into "Doctor Who" from so many on my flist singing its praises, so you're not alone. Though I can't see any bridge-jumping excursions in the future, so you're probably okay there ^_^

I thought Amy might be pregnant when she felt sick at the White House, but then River Song said she felt sick when she was in the tunnels with the aliens and that threw me for a minute. But this will be an interesting dynamic for this season and I'm excited to see how it will play out.

(Seconding the above recommendation for "The Unquiet Dead" from Season 1. You'd enjoy it).
