I'll generally watch anything sci-fi. Even the really dodgy cable shows. I drew the line at "FireFly", but now I'm even breaking that resolution.
With that in mind I've suprised myself by completely failing to watch Dr. Who in its new and shiny BBC incarnation. I watched the first couple of episodes but then just gave up. Until I caved in again and ended up watching the last couple of episodes.
The finish to the series was proper sci-fi with a cool "Phoenix from XMen" type moment.
I think I'll be making an effort to catch the repeats. And if I had kids I'd definitely be looking forward to sitting down and watching the next series with all the kids hiding behind the sofa.
