Until I get used to it, though, it's left this season a little short of the almost unbearable tension that seasons 2-7 generated. With Legacy, so far, the concern is over the thumbdrive with the list of sleepers, who can no doubt wreak havoc, except we haven't gotten a taste of that (other than the initial assassination of Carter's teammates). In season 6, a nuclear bomb wiped out Magic Mountain (the theme park in Valencia, CA), in season 3, we saw lots of outbreaks of the Cordelia virus, and in season 5, the shopping mall got doused by VX nerve gas. All of those were precursors of potentially much worse WMD attacks, giving real bite to the ticking clock -- if Jack didn't stop the threats in time, tens of thousands to millions of people would die.
Again, the threat this season is more realistic (or should I say, higher likelihood), and I expect that as a viewer, I just need to be re-trained to accept this threat level. But if there's one thing that I'd contrast with the Jack Bauer seasons, this would be it.
