The Tomorrow People was great fun when I was a kid and had the most creepy theme tune and title sequence ever. It mirrored some of the ideas in the X-Men comics and pre-figure some of the telepath story themes in Babylon 5. It was a very, very homemade though (even more than Doctor Who of the day) and in reality was nowhere near as good as I remembered it.
Torchwood is one of many spin offs of Doctor Who.
Pinched shamelessly from The Forge stories in the Big Finish audio range only nowhere near as good or clever the first two series were a mixture of bad masks, awful CGI, hideous characters and pointlessly shoveled on sex.
Then suddenly it returned in a single story mini-series where it was actually rather good.
It will return as an UK/USA jointly funded show (probably).
