All the U.S. Filmspotters who have BBCAmerica on their cable/satellite should check out the new Doctor Who tonight at 9 PM. It's a great jumping on point, new Doctor, new companion, new everything. On top of that, it is a really fun episode, works all the necessary introducing stuff into a pretty suspenseful storyline.
Also there's a Doctor Who special to fill in the backstory at 8:00.
All the U.S. Filmspotters who do not have BBCAmerica should find a friend who does.
