I am a HUGE fan of Torchwood and have been talking it up to anyone who will listen.
The best "broad brush" characterization is that it is a cross between "X Files" and "Dr Who." I have liked it so much that I have started watching Dr Who again.

The final episode of the second season [first season was last fall, second is this spring] is next week [Sat, on BBC America] but I expect that it will go into repeats and the first season is out on DVD already.

Strangely enough [and more so now that I know he has one] I have wondered about seeing the cast kilted .
