Yes, it is completely unsurprising when Laura Harris turns out to be the real terrorist, because they pulled the exact same shit with her in The Faculty 4 years earlier!!! It's as if she was being typecast as "the wholesome all-American girl who turns out to be evil" at the time. Ebert's review of that movie is weirdly harsh on Sarah Wynter's posture. I guess it merits pointing out that she's by far the least engaging love interest Jack ever gets.
I always thought Carlos Bernard (who plays Tony Almeida) bore a slight resemblance to Antonio Banderas, more so than Casey Affleck. Speaking of, apparently Ben is also some kind of harrasser? Did that surprise anybody?
Not sure what else to say here. You're pretty much dead-on about the stupidity of Kim's plots (my favorite detail: her hapless boyfriend turning out to be some black belt martial arts master), the lameness of the 25th Amendment plot device, the copout of having Jack pretend to execute a guy's family (just why exactly did that end up working, anyway?)... the first season, while it had its problems, was a lightning-in-a-bottle blend of tight plotting and gimmicky scene-staging, with the payoff of an outrageous shock ending and the second plays like an inferior sequel to it in just about every way. Still, the way I see it 24 doesn't really become 24 until sometime after season 3, with invincible SuperJack busting through walls and torturing the shit out of every possible suspect with impunity (you thought THREE scenes was pushing it?), ancillary characters dropping left and right like flies, and the real-time conceit becoming basically meaningless. In other words, you're in for a whole bunch of treats here that I'll probably spend much less time and effort responding to. Enjoy another round of seasons 1-3 of Arrested Development! You deserve it.
