That's what my husband and I did, Amy. We started renting the DVD's from season 1, and continued until we were caught up. It's on season 7 now. It didn't take us long to catch up. Season 1 is one of the most intense seasons of all!!
It's cool because, each season takes place in "24" hours. It all occurs in real time. So at the end of each hour, you can hardly wait for the next episode. So, each season has 24 episodes, and it's all wrapped up in one day. It's an awesome show, and I highly recommend it. I love Kiefer Sutherland. He's amazing as Jack Bauer!!
