Looks like Farscape missed the cut. It ran for several seasons, had a few movies, and a spin-off.

Outcasts (Brit) was good, but only lasted one season.
Primeval (Brit/Canadian) was good for fun watching.
Aaron Stone (Disney) and Sarah Jane Adventures (Brit — Doctor Who spin-off) were good for older kids (and youthful adults).
Haven
Mutant X
Special Unit 2
Tremors, The Series and the movies
V, the original movies/mini-series
Primeval was a favorite of mine as well.
There was the short lived Starcops from the 80s.
Torchwood was good to, even as creeped out as it could get sometimes.
