I liked it up until the last few minutes. Way too reminiscent of S5 at the end.
No. It really was not - I'm not sure why so many people are comparing it to the S5 finale where Bauer was sucessful in bringing Logan to justice, was pretty much happy as all hell and then was suddenly kidnapped by the Chinese.
Live Another Day's finale shares basically NO similarities to that apart from him going to prison again - but even then, it's under wildly different circumstances.
So no, it's nothing like S5 e24. It's basically a retread of the S1 finale:
1. Fight at the docks at night against an old enemy (Drazen/Cheng)
2. Jack hears news of the death of someone close to him which causes him to go on a killing rampage (Kim/Audrey)
3. Jack kills his enemy mercilessly with pure anger (emptying a magazine into Drazen/chopping Cheng's head off)
4. Jack's lover dies (Teri/Audrey)
The last half of the episode was essentially S1's finale almost beat for beat. And then, Bauer decides to accept the inevitable and willingly go to the Russians to save Chloe. His emotion in the helicopter is of peace and acceptance, and the silent clock signifies that. In S5 he was taken against his will, beaten senseless and was left begging to be killed. Big difference.
