Russell T Davies really took the elements of Dr Who and made a much more "adult" or darker side to th whovian universe. I have loved Dr. Who since William Hartnell and my favorite Dr.s are Jon Pertwee and Peter Davison (from the original series). But anyone watching TW must remember this is NOT Dr Who anymore than it is the Sarah Jane Adventures! The SJA is to kids what TW is to adults. RTD made this pretty clear in the early episodes such as an alien that kills you is you have sex with it. I doubt that plot would be in a DW episode. Torchwood is very well thought out IMHO. It is worth viewing from the beginning if you have the chance. Now lets see the NEW series! :)
