Kiefer Sutherland 주연의 TV 시리즈 물이 4편씩 묶여서 DVD로 나와 보게 되었습니다 (시즌 2).
DVD 하나당 4편씩 들어있으므로 근 4시간이 금방 갑니다. 그런 씨리즈 DVD가 에피소드 1, 2, ... 이런 식으로 복수개가 있으므로 맘 잡고 시간 내시지 않으면 곤란합니다.

중독성이 강한 연재물로 반드시 휴가 또는 충분한 시간이 있을 시에만 보실 것을 권고합니다. 무지하게 재미있고, CTU (Counter Terrorist Unit)이라는 정체불명의 조직의 활약상이 대단합니다. 미국의 최민수 혹은 허준호라 할 수 있는 키퍼 서덜랜드가 아버지를 완전히 극복(?)했다고 보여지는 훌륭한 연기로 시종일관 정의의 사도, 고독한 영웅의 모습을 잘 보여줍니다. 서덜랜드의 딸로 나오는 젊은 여배우는 시종일관 보는 사람을 짜증나게 하죠. 멍청함의 극치로 나옵니다 (순진한데 정의감만 불타는 캐릭터).

경고드립니다. 중독성이 매우 강한 씨리즈물이므로, 연구 중이시거나 시험 혹은 중요한 일이 있을 경우 보지 마시고 스케줄 잘 조정하셔서 보십시오. 테레비가 왜 바보 상자인지, 어떻게 사람을 중독시키는지 실험하기에 좋은 소재가 될 씨리즈 입니다.

보험회사 All-State의 광고에 등장하는 흑인 남자 배우가 미국 대통령으로 나옵니다.
