I finished season 3 on DVD last night. I was very touched by the anguish on Jack Bauers face at the end. He had a long day. Sutherland did a great acting job. I await season 4 on DVD!
If all you have watched is up to season 3 you better be carful what you read on the "count".
It's 100% spoilerific so just a heads up....
Also I love the season 3 finale. Closure was brought forth something the last two finales have been missing. The season 3 finale is maybe my second favorite of the five.
My mom watched season 1 on DVD a few weeks ago, because I told her it's the best show. Just 20 minutes ago, we finished watching episode 8 of season 4. Oh, yeah. She's hooked. She needs to finish it by Friday in order to begin watching the season 5 reruns.
Have fun with season 4! My second favorite season.
