Great finale. Those scenes in the bunker were intense. I really liked how they resolved that situation with Brody and his daughter. That would not have happened on 24.
For next season, it does leave Brody still in the same place as before, without no one other than Carrie (and perhaps his daughter to some extent) suspecting him of anything (and it will take Carrie some time to remember the connection she made). I don't know if that's good or bad.
I did have one small qualm about this two-step terrorist attack plan. If their intention was to take out a bunch of high value targets, why not have Walker shoot the vice president first and let Brody take out whomever was left in the bunker afterwards. That would have a much higher probability of success in terms of eliminating the highest priority targets. Of course it wouldn't work as far as the show's storyline.
