Well, sci-fi is notorious for picking up forgotten series' and playing them as if they are the newest thing ever.
Take Andromedia, for instance, they started playing the old episodes every tuesday. Stoped. Then started again. Now they have picked up John Doe, which was from quite a time ago. And heck, they even play their famed Stargate series from beginning to end on monday and every weekday at 6. Even watch it in the morning somedays to see battlestar galatica episodes (the old ones). Or the crusade (don't think they play it anymore). well, alot of old stuff in Sci-fi.
More convincing is this
http://www.bbc.co.uk/doctorwho/ linked as the 'new' series.
Or mabey not??? Confused now...
Okay, we are seeing the 2005 version? Why change... a character after a year?

I believe society is flawed; our notions on life, on child rearing, stem too far back to be of relevance in this day and time.
