Dr. Who
My brother loved Dr. Who when he was a teenager, and being 9 years his junior, I'd sit there figuring "Well, if my big brother likes it..." It never actually reverberated for me though. Not the way Hitchhiker's Guide or The Young Ones did. The new series, though, is just... wow. There's a few iffy episodes early on (the Dickens one and the Sun exploding ones aren't quite up to snuff to the stuff that follows), but the past three episodes have been some of the best Sci-Fi television this side of the Prisoner. I think it actually puts Lost to shame. The show gives resolution, a feeling of progress, and character development. Lost, while the character beats, and the plotting from episode to episode is interesting, just never delivers, and, well, most likely never will. It's the nature of the beast, and a core difference between the shows.
The Doctor is Batman. He's Superman. He's James Bond. Except, they even came up with a decent enough explanation for why he's always changing actors.
Anyways, my point is that I think a lot of people are like me and have less than fond memories of the original (which, as i've been watching some aren't actually quite as bad as I remembers, and some are actually quite good), this is a totally new, totally seperate beast, and some of the best Sci-Fi currently on the TV.
