I don't know what's worse, the nuke or the fact that Jack Bauer is having a nervous breakdown. I wonder if they're fixin' to give him some "down time" in the series. That's the TEST of a mega-hit series: It can survive the death of the prime character. Can somebody give me a list of the key players killed off last season? I stopped watching after a mole in CTU killed Jack's wife. So, who's died since her (Mrs Bauer)?
President David Palmer, and Michelle Dressler were killed in the first five minutes of season 5.
I saw a special on E! channel, and they said that Kiefer Sutherland has signed on for two more seasons.
IMO seasons 4 and 5 were far better than the previous three. Get them through Netflix or amazon.com. You'll be hooked again :-)
