There's a new Doctor Who series and so far, it's awesome. Obviously since we're in an entirely new decade for Doctor Who, the special effects are an order of magnitude better than you've ever seen. The Doctor is in his 9th regeneration and is played by Christopher Eccleston. His new assistant is played by Billie Piper (yes, this Billie Piper).
With this show, and the new Battlestar Galactia, I have renewed hope for SciFi on Television, even though Enterprise has been cancelled just when it was getting good.
