I'm not that big a TV watcher, but I'll contribute where I can.
I tend to watch sci-fi. Specific "areas of expertise" include:
- Star Trek TOS, TNG, DS9
- Battlestar Galactica (the new "reimagined" show)
- Doctor Who (the new show, since Christopher Eccleston)
- Torchwood
- Stargate SG-1, Atlantis
- Buffy the Vampire Slayer
