Torchwood is worth a try. Because it's aimed at a slightly more mature audience it's got less of that high-energy, camp feel that I love about Doctor Who but sometimes I think the acting and writing is a little better. Because the Doctor isn't there using his big Timelord brain, when there's a real threat more feels at stake. Like the episode Dalek, where one Dalek was terrifying. Torchwood is like that a lot of the time.
