There is a show called "Eureka" (also an unrelated anime.. which is also good )
very good. It is not your traditional scifi. Takes place in a small town of scientists which are contracted for the DOD and things just go wrong... PRetty good and lots of humor.

Another show.. Actually mini series is "The Lost Room". It doesn't have robots.. doesn't have space ships... bits of humor. The acting is a bit sucky.. But the story, and the concept is Amaaazzzzing!

I agree with ventilator about Sarah Connor Chronicals.. It is pretty entreating, and the last episode in the series is really cool!
