i have see the first four season and i must say it one of the fine tv series i have ever see . if you like thrill action on the screen and you _must_ see this . jack bauer be a great character and but i be also very impressed by president palmer and whose wisdom and calm and dedication to his country shall stay a an example for each people on this world who play a leadership role . besides that and the team spirit in the ctu and despite the high pressure and extreme situation theyre facing be absolutely fantastic . i hope there will be a season 6 and 7 and so on and i be look forward to watch them . actor and crew and producer and a big thank you for make this happen .
