I'm working my way through season 3 of 24. Of all four seasons, I'd say it's my least favorite, but I just got done watching an hour that was probably the most disturbing of all the TV I've seen. Michelle says goodbye to Tony because she's presumably gonna die, then Jack has to kill Chappelle. I didn't even watch the last part, because I remember being too freaked out by it the first time.
I look forward to watching season 4, which is more about the kick ass "holy crap!" moments. Also looking forward to the new season in January.
If you're not watching that show... you're missing the best thing on TV.
