I thought it was a great season, and a great season finale. Many unpredictable twists, for an action series atleast.
And I really enjoyed the overall theme painted by the finale. It tied everything together perfectly I thought, and sent a fantastic message...which, again...for an action series is pretty cool.
The theme of the price of vengeance, which we saw everyone dealing with. From Olivia, to Renee, to Tony and just seeing how deep they're willing to fall for it.
I actually thought Tony was somewhat redeemed in this finale, because even though he was the bad guy for a while...he had a pretty damn good reason for it.
The Kimnapping was not a problem. It only lasted like 5 minutes.
Powerful scenes too. Tony's scene where he revealed that he had a son on the way was powerful. The Presiden't scene with her family, her husband specifically, was powerful too. Renee making the choice to do what she needed to do. And Jack searching for peace of mind in some way was pretty cool too.
I thought Kim's line was pretty cool too. Since as a viewer, I too can't let go of Jack Bauer just yet.
