I'm willing to bet that this season will end with Jack being abducted by the Chinese. Just when it seems like the show is over a car will come flying in and he will be grabbed. It will set up next season but we will spend half a year waiting to see what happens. Like you, this is the only show on TV, besides sports, that I am hooked on.
Also, like someone else said, I too hate the President on this show, I wanted Jack to punch him in the face after Walt Cummins got hauled away.
