Terminator: The Sarah Connor Chronicles (Fox)

TERMINATOR: THE SARAH CONNOR CHRONICLES picks up the Terminator story a few years after the events of the second movie. In the show, Sarah (Lena Headey) and her now-teenage son John (Thomas Dekker) are on the run from both the authorities -- who think the Connors are responsible for several deaths -- and from the Terminators, which have never stopped hunting them. With the help of Cameron, a Terminator sent back by the future John to protect them, they decide to stop running to prevent the creation of Skynet, which launched the war on mankind in the first place.

One of the most fascinating mysteries of the Terminator stories has always been how Sarah Connor raised son John, who is destined to lead the human resistance in the future after humanity loses its war with the murderous machines. The show fills in that gap, showing how she taught him the skills necessary to fight back and win against a seemingly unbeatable enemy. This chapter of the Connors' life is much better fodder for a TV series than a simple rehash of the films' standard chase format would have been -- the result is smart, nuanced, and very satisfying.

That said, this is a Terminator show, so there's still plenty of action and excitement. Cameron (yes, her moniker is a shout-out to James Cameron, who created the franchise) regularly ends up duking it out with her robotic counterparts. The interactions between Sarah and Cameron (Firefly's Summer Glau) are especially fun; these two powerful women dominate the show. By contrast, John is young and unformed, and though he's the focus of the storyline, he's the least interesting part of the show.
