Kidnapped has been cancelled -- they'll complete 13 episodes and wrap up the storyline, but then it's over:

Personally, I don't like disconnected shows at all -- with the exception of sit-coms. I want to be engaged by the story, not by a set of single-serving episodes. I think that's one thing that makes Joss Whedon so popular (Buffy, Angel, Firefly) - he wrote shows that could stand alone but also fit into a bigger picture. There's a minor thread and several major threads throughout each season. Excellend writing. Prison Break is similar in that regard. Veronica Mars is another excellent example (and HIGHLY recommended).
Of course it helps to have TiVo...
