As for Dr. Who, I love the new guy. His "We're all in grave danger!! FANTASTIC!!" attitude is great. His side kick doesn't do anything for me but she'll do. Hopefully the new guy they picked up from a future Utah will add something more to the equation. All in all though, I think it's quite good. Very much in spirit with the original series.
I love sci-fi! Here is a list of my pet-peeves after years of viewing different shows. I wish they would change some storylines sometimes...:
1) No more "evil double" stories. (BSG is forgven considering the robot doubles running around)
2) No more "I'm invisible and no one can see me but I am not dead so I can hear what everyone thinks of me" episodes.
3) No more "I am getting old and will die of old age within and hour but I will get cured byt the end of the show" episodes.
4) No more "I have been possesed an alien/spirit and for a little while to use your body as a vessel" espisodes.
5) No more "I wake up in a dream and think its my reality (lasting days or years) only to find out at the end that it wasn't real" episodes.
