Have to give it my thought
The production went a little crazy the last 2 seasons with providing a climax EVERY hour. I guess it's good in a sense that you are on the edge of your seat weekly. Then the timing factor came into effect with several argumentative call. I also didn't quite appreciate that they kept adding people throughout the story. I guess they wanted them in to keep the story line going. I prefer how they tie in the old characters mentioned before i.e. Christopher Henderson whom Jack ratted out on, the Chinese Consulate who knew Jack is not dead, Mandy from season who should be back next season after she got the full ammunity from Logan. I didn't like how they brought out the group people at the end. I prefer them out sooner right after we found out that Logan is in all of this. I have mentioned it before. I much prefer they bring out fewer climaxes but focus on building those climax in a few epoisodes. This way, I can focus my attention more on what's going to happen next week over on wondering whether what's happened can really happen with such short period of time.
But after these said, TWENTY-FOUR STILL ROCKS! Never mind season 6, 7, 8. If Friends can last 10 seasons, I think 24 can last maybe at least 12-14 seasons.
