Eh what happen sardaukar? I thought season 6 is one of the best?
Heh, far from it. I think for the most part it's because there are only so many ways to threaten the US population (nuclear, chemical or biological), only so many ways to undermine CTU/the White House (incapacitate the head, have a traitor, have a coup) only so many ways for Jack to be cut off from his CTU resources and have to act rogue, and finally, and hardest of all, only so many ways for Jack to actually
need to be the one in the middle of the action--because certainly there are many more agents who should be able to do it.
All that being said, once season 6 came around, it necessarily had to be made up of bits and pieces from previous seasons. And certainly losing a lot of the main characters didn't help one bit.
