"24," which begins Season 6 on Sunday night at 8 , is electrifying, and completely silly. It's a show that walks -- no, sprints -- the line between grim suspense and the Keystone Kops . As Jack Bauer wards off apocalypse after apocalypse, the action is as lean-forward-in-your-chair riveting as it is ridiculous, as much a contemporary-anxiety nightmare as a cliff-hanging comic book.
In other words, "24" perfectly captures the mood of America, so poised between global eruption and political farce. Whatever you think of Fox's terrorism serial, which returns on Channel 25, it is sure to go down in the pop-culture history books as the emblematic show of its time. "24" is a by-any-means-necessary, Bush-era fantasia that celebrates American persistence while turning that persistence into a rabbit chase. Jack may bag a terrorist mastermind, but he or she is always fronting for another mastermind, and so on ad infinitum. Pure evil is always just out of reach on "24" -- hiding in a cave, say -- and destined to reappear as the next villain-of-the-week.
