***OMG SPOILERZ!!111!!***
Man, the destruction of the nuclear missile and the death of the terrorist mastermind were kind of anticlimactic. I expected 'em to be all dramatic like a James Bond movie. Also, anyone watching the show who thought that Tony was killed in the explosion should not be allowed to roam free on the streets. It would've been better without the whole "let's show the terrorist abducting the neighbors" scene.
My prediction for next season: Based on the "crossing the border" comment, I think Jack is going to become a mountie and fight terrorist caribou.
UPDATE
Something just occurred to me...what the crap happened to Behrooz? He just kinda disappeared. I guess they killed him.
