The first 4 seasons were so incredible. It was a tough premise to keep up though. Cracks started appearing in season 5 and season 6 just became down right ridiculous. But Jack Bauer is one of the best TV characters ever created and Kiefer Sutherland was born to play this part. This show was the definition of serial thrill ride. My friends and I used to have weekly viewing parties and if you broke the gag order on spoilers you were dead to us. Some of the funniest times I've ever had watching a show. It was more like an experience.
