Dance Machine (7 p.m., Ch. 4) and Duel (8 p.m., Ch. 4): If you're desperate for something new, ABC airs original episodes of these two lame shows.

Doctor Who (7 and 9 p.m., Sci Fi): The Doctor faces danger on a pleasure planet.

Stargate Atlantis (8 and 10 p.m., Sci Fi): In the fifth-season premiere, Colonel Carter leads a rescue mission. You've got to be a fan of the show to appreciate this.

Flashpoint (9 p.m., Ch. 2): CBS bought this Canadian crime show during the writers' strike and is finally airing it during the summer. It's not bad, but it's nothing special, either. It's about an elite police team in Toronto that tackles tough situations. In the premiere, they deal with a hostage-taking and its aftermath.
