I'm a true fan of Dr. Who, though I have to admit, I'm not of the level of dressing up as a character. And yes, "the plots were cheesy, the acting was terrible, and the prop and set budgets must have somehow involved very unsuccessful panhandling" are all true and I still liked it, alot.
I also loved the Prisoner, though I haven't seen it in years, I have fond memories of it. There are several old series that I wish were in constant reruns like The Prisoner, The advengers, Mission Impossible, Man from Uncle, Dr Who, rather that than stuff like Sanford and Sons; or Leave it to Beaver.
I'm sorry, but the few episodes I've seen of Torchwood have not impressed me. While I have enjoyed Santuary, I can't see how it can conceivably become a long-term series.
