Go out and rent the first season. Watch the episodes in a marathon like format over a 3 day weekend.
You will be hooked.
24 is the best show on tv!
I have all 4 seasons.It so cool when there is nothing worth watching, you can put on 24 and you be in front of the TV for hours.Jack makes the show,the writers are so right on about what goes on behind the scene's in the fight against terror.I saw a show on Fox with a couple of the cast members talking to some CIA folks,They said (CIA)was surprised at the parity of reality to the show 24.I hope it runs for many many more years to come.
