24 is a much better example than Fringe. If Fringe depicts torture as a tool, it also depicts time travel as a tool and wacky science as a tool, but I don't see the author taking umbrage.

Fringe, like 24, is a work of fiction. The problem is not the series' content. The real problem is letting politicians and media use a work of fiction as an actual situation. Using "Jack Bauer" in the debate about torture is like using Planet of the Apes in the debate about space exploration.
